I'm glad I found this thread, as I was trying to do the exact same thing as @sab0t.
I'm kind of wondering the same thing now, and the answers above don't really satisfy me. Other than a low powered / solar powered GPS beacon, or maybe a wireless relay, what are micro-controllers good for? in RL their job is to control devices and machines, hence the name. Why is this functionality removed from micro-controllers in OC? I don't get it.
