Sry for the delay... I'd volunteer if e.g. Vincent would agree to help me with that. He has a Surface Tablet and he has some experience with win8 due to working on coapp. What i wonder is: Do we have enough to tell? And is there more to tell?
I'd certainly help, as this is very interesting to me.
I don't have a great deal of experience with win8, but maybe by FOSDEM there will be more to talk about? For right now, it's a lot of speculation, and the only solid thing I know we have is Andre's work with real ARM desktop exe's on Wine.
My impression is that there aren't a lot of gaps in the RT desktop that Wine could fill in, even if someone jailbreaks it so we can run non-MS desktop exe's. Opengl is conspicuously absent, but we can't help with that.
I suspect the LGPL keeps us out of the Win8 app store, so even if we could technically help there it's probably not a real option.
