A post by Epic's Tim Sweeney on SourceForge opens the possibility that Epic would be willing to cooperate with someone willing to do a port of Unreal Tournament to the BeOS (thanks BeBits). Here's the scoop:

The parts of the engine you'd need access to for a full port aren't open-source right now, but if an experienced team or individual came to us wanting to do a BeOS port, we'd seriously consider giving them access to the complete source for that purpose. Know anyone? :-)

I get several emails each week from Be users wanting a port...
