How much work is required on specific UT stuff now, I mean once we get that vanishing mythical unicorn of a mainlined Linux kernel which serves both Android and GNU Linux. Then we can all have horrible bin drivers for at least one kernel version of everything. Kinda like the situation we have with the Maemo tablets and phones.
AFAIK the mess of UT is mostly due to android specific video drivers requiring surfaceflinger and whatever does android sound and having to do a localhost VNC for video kludge/hack to (badly) run normal x11 apps.
