Well, I suppose it's possible to compile a Steam version out of the current sources, but it's stripped of most Steamworks code, and Steamworks is only available under an NDA. So the only one who can make a Steam version is Alec, if he's interested. (BTW, the sources contain sample Steamworks code for achievements. It shouldn't be too difficult to integrate Steamworks back into the code. The only problem is it can't be open sourced, unless Valve is fine with having function calls without headers floating around on the tubez.)
