That would mean decoding the 3rd party remote's protocol and fooling it
into thinking it was talking to its own device, rather than just putting
buttons on PIC pins. Plus, how easy/cheap is it to get hold of these

That's a good point. It'd be OK for a car adapter, which is one thing I
would very much like to use it for, but for portable use it'd be a
little trickier. Unless you could hijack the JB battery power with a 4
core wire/connector somehow.
Maybe it IS "back to the drawing board"...
