23 % is not very much, I think. Also, you shouldn't forget that bzip2 is
very, very slow. Uncompressing the Packages.gz file on a slow machine
already takes several seconds, it could approach the minute with bzip2.

And it does only gain 23 %... What about a "light" Packages file,
containing only the names and versions of the software, and a Packages
file for each source package (one of the proposed solutions to the
growing Packages.gz problem) ? You could strip the daily download down
to about 100k.

One really interesting about bzip2, in fact, would be dpkg-source
supporting it, as an increasing number of upstream authors use it.
