Most toy and model R/C interfaces use pulse-width modulation. You could
simply send that data stream into the RCX which would take a fair amount
of software decoding (I doubt you could do it with the Lego Firmware - you'd
C and LegOS or something).
If you could pull it off, you'd get up to 8 analog inputs with high end radio
gear...fewer with cheaper equipment...using just a single RCX sensor port and
without having to use tricky analog communications strategies. That should
also be easier to implement hardwarily too.
