FYI-- I posted a crummy Alpha version of my NeoMattie (Nemod Lite) plugin for Linux over here:
http://www.mattie.info/cs/forums/viewtopic.php?t=1768
It's quite broken, but some commands work (e.g. nm_spawn, nm_gravity, etc). Still working on it.
Anyone else who actually has the old Nemod fully working on Linux, definitely post a link. I'd love to see it (and so would everyone else).
