/me wonders if you could put a low-pass filter between the two circuits
(I have seen these discussed in X10 forums), and then pick a spot in 
house with easy access to both circuits and put an ethernet bridge 

That is:
* Keep circuit A and circuit B electrically isolated.
* Connect a EOPL adaptor to circuit A.
* Connect a EOPL adaptor to circuit B.
* Connect ethernets from both to a switch.
* Switch bridges network "powerA" and network "powerB".

It ends up using 2 more EOPL adaptors, but the speed and latency would
not be so bad.
