Well, since you said that Insteon signals mess with the threshold of the
X10 side I assume that the uC can't keep them apart. If they come in
concurrently and on the same line it really can't.

Unless you can gate time slots the only other option I see is to provide
a 120kHz filter plus demodulator and feed that into one port, then a
131kHz (or whatever Insteon uses) filter plus demodulator and feed it
into another port.
