I may join and bring e.g. some of my n810/n800 controlled DIY USB hardware like the i2c-tiny-usb and the tiltstick. But since our second child is to be born end of august i can't guarantee anything. One option would be to bring my then 18 month old daughter with me the 500km to berlin. She really likes the n810 and enjoys video conferencing with her mother between bedroom and living room. But she especially enjoys pulling out the n810's stylus and carefully putting it back in place.
