I'd like to see that implimented for Linux ... I'm planning installation of
Linux on a 386sx20 with 4mb of RAM and 40mb of disk space, which is a rather
masochistic task (at least we'll be using someone else's newsserver :-).

I'd be willing to test the patch if/when it's created.

Another idea... possibly have it run as a daemon? That would be easier for
me (and other low-disk users) because there's no room for compilers or linux
source on a 40mb disk. It could run kind of like kerneld ... uncompress files
as needed, and recompress when done.

Just my 6 cents worth (adjusted for inflation)... -rt
