Yes, this is what I've been thinking about for my palm-top serial
connection idea. Of course, I probably ought not to be touching this
thread with a broom-handle, since I still haven't gotten round to
teaching myself C++...

I think I read somewhere that it's actually a physical switch inside the
socket. Notice if you plug the charger in, even without the charger
connected to the mains, the unit starts. If that's true then this isn't
a viable option.

Yes, this is another thing I've been thinking about. ROLO is pretty
damned fast at loading firmware.
