MeeGo 1.2 is much improved over what was available last year. As you know, open source moves fast. That's interesting you got your touchscreen to work out of the box in ubuntu 11.04beta. I tried it on my desktop and my igep (both with 11.04 final) with my xenarc screen and it wouldn't calibrate correctly. Others are apparently having the same issue.
I saw on your website that you made a python app for the fusion brain. I'm surprised to hear that fbd was too slow? I'm curious how high resolution data you needed... There are a couple things we can easily do to fix it. fbd solves a major problem in linux and that is how do we multi-plex access to the fusion brain to multiple processes. I'm interested to hear how you solved that and the speed issue in your implementation.
I know you already have a pandaboard. I was just checking out the snowball today. Looks like it one-ups the pandaboard in just about everything. Comes with sensors too!
