Ok, delta debs might be great for updating, but when downloading a new package, we need a compression.
In Windows, when you download a program generally it is in a rar. We should make the repositories to send the package compressed and then decompress it for then installing it.

Debs are compressed.
http://en.wikipedia.org/wiki/Deb_(file_format)
Debian packages are standard Unix ar archives that include two gzipped, bzipped or lzmaed tar archives: one that holds the control information and another that contains the data.

That's only about the Packages files and the CD content - not the whole archive (not to mention that it seems abandoned).

It was meant primarily to save space on the CDs, but applies to the whole archive.
This change is being proposed primarily to save space on the CDs. It would also save bandwidth for downloads from Ubuntu servers.
Launchpad will need to be modified to support lzma uploads and to check that the needed predepends listed in the package.
I linked to it for informational purposes; not sure about the status of deployment, despite the "Implementation" field listing "Deployment".
Well, looks abandoned. Thanks.
If you open a .deb file with the archive manager, you will see that they are compressed.

If you read the full spec they do give figures about how much would be saved in the archive. Don't know if those are real figures or projections.

Only the DVD and Alternate CD include .deb files, correct?
