Indeed.

Konrad, what is the exact requirement here? You mention socat which just
takes an IP address and connects to it and pipes stuff back and forth
(crypto optional). I suspect the sending side of that can be done with a
thin wrapper which provides the 'ssh like' command line interface, so
what is needed is a daemon listening on a known port which can fork +
exec xl migrate-receive for each connection?

Is socat actually what you want or was that just an example?

Ian.
