Hi, are you still working on packaging rdesktop? I noticed that, though it's GPL, it contains a few files with a non-free license (crypto/arith.c crypto/arith.h, crypto/conf.h). If you're interested, I've got a patch to get rid of them, so rdesktop could go into main. I've also got the whole thing debianized, if you want to take a look. I'll have it all uploaded to http://people.debian.org/~btb/src/rdesktop/ pretty soon.
