That's what I had thought as well, which confused me. There's no MT
support in X yet, so how does Xnee now have MT support?

We (Canonical) haven't had a chance yet to build a test harness for our
utouch stack, but it's going to be one of my main tasks for the next
couple weeks. I'll be looking into Xnee, evtest-capture, and the test
tool that Henrik has been hacking up. If Xnee is at the X level it may
be too high up for what we want. We need something we can feed events
through as though they came from a real device, with all the quirks that
a real device may offer, like ghosted or dropped touches.
