unless there are another versions of the H8 that have more
inputs/outputs (?)
I didn't know it was processor limited. Maybe they can do some sort of
multiplexing. (At least for inputs) That way they could get 2 or more
in the space of one. But you do see the need for more outputs right? I
would LOVE 'em. :)

That sounds too good to be true :)
I heard they couldn't have the radio link in the RCX becuase of FCC
regulations. I agree that radio is MUCH better than this line-of-sight
IR.
