Okay I have two main worries with this project,

a) I'm a lousy mentor, between timezones and workload I'm not sure I
can commit to spending much time on this, but hey maybe I can make
myself, if you only ask questions I know!

b) I think the project as-is is too big a target, I think I'd probably
aim for something a bit lower, maybe just getting shattered rendering
in a multi-head Xephyr, so you'd have the impedance layer and two
Xephyr GPU screens, and you'd run a bunch of tests like xts and
rendertest over the shattered rendering as a final goal. Polishing the
impedance layer would be a major start, also things like how GLX or
DRI might work should be considered but along with Xinerama I'd put
these as a bit of stretch goal, as I expect it will take a fair bit of
time to get up to speed, I spent at least 2-3 SoC equivalent man hours
on this, and I only got it some of the way.
