Yes, don't fall out of your chairs yet. Here's Canonical being rather decent about upstreaming. Multitouch seems like exactly the kind of thing Canonical ought to be working on, and they're taking this upstream at the right time and with the right approach, AFAICS. That's exactly what I was talking about in this other post. I can't tell whether the proposal is awesome or crack, I'll leave that to the experts. But the process here looks awesome. So nice job with that one.
