Technically sufficient, maybe, but it might be actually illegal to install 
Direct X on anything non-windows. Of course the blame is shifted to the user, 
but if one thinks about corporate wine deployments, they wouldn't want to do 
illegal things. They might as well deploy pirated Windows, you know. And mind 
you, Direct X is not for games only. I bet there are non-gaming 3D 
applications that use it. CAD systems come to mind. I think that for example 
Solid Edge uses Direct X (no, didn't try to get it running under wine yet).

Cheers, Kuba
