A few comments:
* Doesn't jack2 have this built-in ? I seem to remember something called
'loopback ports', but it has been some time...
So you start jack2 with the required number of loopback ports, then
connect A -> writable side of loopback ports, and readable side -> B.
* Since this is just a buffer, the '-split' name seems a bit misleading.
* I'm not convinced that the logic used in your current implementation
will do the right thing in all cases (but I could be mistaken).
The reliable way to organise this would be to use a dummy port in
reverse direction on both clients and connect those.
