Once the hardware support comes it'll just work. You can definitely
run it at the moment, but need to modify linux to get it running - so
this means no windows. Once hardware support is here though it'll be
great - work on linux - open up grdesktop to grab a remote session to
windows and do your photoshop/whatever in there. Also means a
renderfarm could run software which is only available on windows and
still have linux available.
