(A late) Thanks for the explanation! So am I getting your vision right: to have a sort of 'server' which runs pd patches and an editor which only edits patches and submits them to the server to run? Plus I guess dynamic patching and changes graphical objects' attributes which will make it all more complicated...?

Actually I am thinking more of two separate instances. One is headless server if you like, the other one is fully integrated system/editor that also encapsulates the server. This is because as soon as you start transporting things over a socket, any busy gui stuff, particularly redrawing large arrays, becomes a terribly slow feat. OTOH, the system would still have to be threaded to prevent gui from messing with the engine, so to say. I think this is essentially how Max works but I honestly don't know for sure.
