Hi maddin!
As far as I know, this is not currently supported at all.
You can (I wouldn't really recommend it right now) write a script that takes orders from a remote client (look for SimpleXLMRPCServer in the Python docs) ; however, you still have to start it manually, it isn't very easy to use, and it still needs a running X11 session.
If you manage to do something about it, I am interested in hearing about it!
Cheers,
