Hi, I'm kinda new to LUGNET, so if I get this wrong - sorry! I'm interested in this LNP idea that seemed to be floating around a few months ago. Is it still alive, and if so what state has it got to?

FYI: The simple-rover example uses an unsafe test value for touch sensors. Touch sensor should be tested against <0xf000, NOT <0x2000 (e.g. simple-rover.c) Reason: Not pressed has a constant value >0xf000. Pressed varies depending on battery change, (...)
