Without knowing fully what the future holds. I would look at Xen advanced
graphics support being provided through a combination of PV drivers that
interface with SDL or some remote display technology like NX (or both).
I would also think OpenGL library support would come through the Mesa
framework in some fashion.
These are just obvious choices that I am hypothesizing about.
