I'm talking about _uncompress_speed_.

Since BenC already has bzip2 .deb's implementedm in pure C, going through
some shell script to make them work instead is obviously going to be slower.

You're going overboard. Debian should not use compression methords like rar
that are non-free. Nor should it use archive formats, like rar, that do not
include unix permissions and ownership information. 

When a good unix fractal compression format comes along, we can talk.
