Detect clients connected to a MIDISource

Hey, all —

Can the CoreMIDI API list the applications connected to a virtual MIDI port
created with MIDISourceCreate?

Alternatively, is there a way to know if no clients are connected?


Background:  I'm using a similar function with a licensed Windows driver to
assist my users in setting up my stand-alone app.  The driver allows me to
get process IDs for all clients, which I can use in turn to get their
names.  Ideally I'd like to be able to say "connected with GarageBand" but
it's even more important to be able to pop up guidance when nothing is
connected yet.
