Is there any possibility to remove the "turnaround" leg or whatever its
called at the X100P?  I'm just thinking of a scenario where none of the
outgoing signal is ever introduced to the incoming circuit.  That way,
the echo problem simply disappears.  Or is this not possible?  What if
the X100P were modified to do this in hardware?  Go ahead and let it
"balance" the circuit if that is necessary, but then not introduce any
of the outgoing signal onto the incoming circuit.
