In some of my mind-trip I've been adventured in a land of disk space / bandwidth saving land. The idea at the base is that in portage exists more version of a package and that this version (expecially for large builds) differ on a very low percentage of code.
the wasted mind come out with:
keep for every ebuild at least a couple of files of three kinds
0) whole package compressed file, 0comp from now
1) "diff -dNr" patch from 0comp, from now 1diff
2) list of files of that package, 2list
I didn't have to change my gender to read your post but must admit I lost myself halfway: I'm not a dev :-) ...
Maybe http://sourceforge.net/projects/deltup/ is what are you searching for? It is not actively developed since it was striped out of official portage tree (last release date Oct 2004).
You can find more about deltup in bugzilla records too.

It was something similar to that, I was thinking about do it patching source not binaries, thinking that patching binaries is difficult (both for cpu and to reach good compression level).
It seems that's not true, seeing his results, also reading that remembered me that there is a md5sum problem (that can be resolved) in all this stuff.
Also it seem that is an old aged idea, that has never take place, can someone please explain me why ?
Ciao francesco
