Hi Jeremy,
Sounds like just the thing we need! Imagine how small the sensor boards can be made? I've been thinking of a Minimal TINY, with limited servo outputs, and reduced size and weight. I think Ublox has some even smaller GPS receivers ( NEO2? ), so I'm guessing the TINY can be made tiny"er"!!
I hope Martin chimes in soon!
Gotta crash now, Good night!
