Hi everybody,
If some one is interested, I've manage to make both remastersys and wubi working together. I'm using a self modified version of wubi and remastersys. First part is for Wubi.
Wubi is designed to use embedded files. The content of this embedded files is filled at compilation time. For my needs, I want a 'none power user' to be able to backup an existing system as a live CD with installation features and why not wubi features. The main problem to do this was the need to setup and compile Wubi each time a new livecd is build. Now, you only need to do it one time.
The first step is to modify wubi to use external isolist.ini files. [INDENT]To do this: If not installed, download packages necessary to compile wubi
sudo apt-get update
sudo apt-get install build-essential unzip p7zip-full bzr-svn bzr gettextand depending of your installation, maybe some other packages
Download the wubi sources.
More explaination are given in http://ubuntuforums.org/showthread.php?t=682751&highlight=wubi+compile if needed
mkdir wubi
cd wubi
bzr branch [http://bazaar.launchpad.net/~ubuntu-installer/wubi/hardy](http://bazaar.launchpad.net/~ubuntu-installer/wubi/hardy)
cd hardy
Compile wubi without modifications to check if everything is OK
sudo make prerequisites
note: when running this command, it stalled when trying to download libcurl sources. Maybe it because of a maintenance roll on the http://curl.haxx.se site if getting this problem, edit src/metadl/Makefile and change http://curl.haxx.se/download/ with a mirror (eg http://www.mirrorspace.org/curl/)
make clean
make
make test
If every thing is allright, modify the wubi code to use an external isolist.ini in wubi/src/variables.nsh add

Compile the modified wubi

Now you have a wubi executable able to read an isolist.ini located in the same directory than the wubi executable itself. By this way, your don't need to compile a new wubi executable everytime you are creating a new live cd. It is now very easy to create this isolist.ini to suite your own live cd. The easyest way to do it, is to make it being automaticaly created with remastersys. The new wubi executable comes with a new command line option "--plugin_ini" to keep compatibility with build-in isolist.ini
What we need to use wubi with a live cd is [INDENT]- wubi executable on the cd tree
This isolist.ini must be formated with distro name and version informations.[/INDENT] Second part, modifing remastersys [INDENT]As said before the isolist.ini will be created during the liveCD creation process with Remastersys. First step in remastersys is to create new parameters that will be used to create the isolist.ini file
- a correct isolist.ini in the same directory than the wubi executable[/INDENT]
To create a live / dist cd remastersys use a CD label, and an iso file name. [INDENT]- Cd label will be use as the the distro name.
in remastersys_gui in fonction modifymenu () add
- version don't exist so we need to add it[/INDENT]
elif [ "$MODIFY" = "g" ]; then
ISOVER=`$DIALOG $TITLE"Remastersys Backup" $ENTRY $TEXT"Enter new revision" $ENTRYTEXT"$ISOVER"`
if [ "$ISOVER" = "" ]; then
ISOVER="0.0.1"
fi
elif [ "$MODIFY" = "h" ]; then
WUBIURL=`$DIALOG $TITLE"Remastersys Backup" $ENTRY $TEXT"Enter URL to use with wubi" $ENTRYTEXT"$WUBIURL"`
if [ "$WUBIURL" = "" ]; then
WUBIURL="http://something"
fi
and modify line
MODIFY=`$DIALOG $TITLE"Remastersys Backup" $MENU $TEXT"Please Select which option you would like to change?" a "Username = $LIVEUSER" b "Title = $LIVECDLABEL" c "Filename = $CUSTOMISO" d "Working Directory = $WORKDIR" e "Files to Exclude = $EXCLUDES" f "CD Boot Method = $CDBOOTTYPE" q "Go back to main menu"`
to
MODIFY=`$DIALOG $TITLE"Remastersys Backup" $MENU $TEXT"Please Select which option you would like to change?" a "Username = $LIVEUSER" b "Title = $LIVECDLABEL" g "Version =$ISOVER" h "Url =$URL" c "Filename = $CUSTOMISO" d "Working Directory = $WORKDIR" e "Files to Exclude = $EXCLUDES" f "CD Boot Method = $CDBOOTTYPE" q "Go back to main menu"`
add also the new parameter in the remastersys config file template in the same file (below cat > /etc/remastersys.conf <<FOO)
# Here you can give a revision number
ISOVER="$ISOVER"
# Here you can give a URL to use with Wubi to download the iso
WUBIURL="$WUBIURL"
Now that this parameters are created , they must be filled to suite the X.Y.Z format needed by wubi
For convenience, the iso file name will be compose with the file name given plus the version plus ".iso":it no more needed to add the file extention
In remastersys, add some code to create isolist.ini first create /etc/remastersys/wubi directory and add an isolist.ini template in /etc/remastersys/wubi

cdmd5sums=md5sum.txt
If you want, add also an autorun.inf in the same directory to get autostart cd features
[autorun]
open=Wubi.exe
icon=Wubi.exe
And the most important, copy the wubi executable you get in first step to /etc/remastersys/wubi/wubi.exe
Now it is time to add some new stuff to remastersys after
if [ "$LIVECDLABEL" = "" ]; then
LIVECDLABEL="Custom Live CD"

add
if [ "$ISOVER" = "" ]; then
ISOVER="0.0.1"

another modification (not related to wubi usage) is to be donne in part step 5 of remastersys to make persistent mode available with ubuntu 8.04

If every thing is ok , remastersys will be able to create some backups/live/dist CD that can be installed easyly in XP/VISTA PC's with wubi
In addition, some little thing may to be done to work properly: [INDENT]- it seems that lupin-support / casper-lupin need to be installed on the system before creating the live cd with remastersys, even if , like it done in the modified remastersys script, a mini repository with the package is embeded in the live CD
- depending the way boot menu of the livecd is set by remastersys, add options to start live cd in installation mode. Here is the config file I am using with my customized gfxboot bootmenu manager

This howto have been written after the job was done (and worked), maybe some small mistakes may be found in the codes given. Any feedback will be welcome in order to correct this post.
One usage I have done was to install UbuntuStudio (Ubuntustudio distro CD don't support wubi) on XP computer with wubi. [indent] -Virtual machine installation of UbuntuStudio -Wubi enabled live CD with Remastersys creation -Ubuntustudio installation on NTFS partition with wubi [/indent]
