The Darwinia Website (thanks Frans) has word that the Linux edition of Darwinia is complete, along with the Linux demo for the evolutionary strategy game. The demo is a 14 MB download, while the Linux patch is a mere 3 MB download, though this, of course, requires the full Windows retail edition of the game as well. Word is: "Compatible with Suse 9.1, Debian/Sarge and Debian/Sid, Redhat 9.0 or later, and most recent linux distributions."
