For the out of process comms OSC seems like a good candidate. We've been
using it for a new linux focused stopgap softsynth api (DSSI), and it
seems to be working well, though its a bit early to tell really. There are
4 or 5 synths that use it.

The mechanism is that the UI is lanuched with the URL of hte hosts OSC
method root as an argument (eg. osc.udp://localhost:4444/foo/bar) and the
UI then reigsters with the host (to tell it where it is) and the host can
send messages to inform the UI of parameter changes + tell it to (un)hide
etc., the UI can send parameter change messages to the host.

The exact mechanism is documented if anyone cares, but it probably doesnt
matter right now.
