Comment 4 for bug 319386

I just came across some information that explains a standard for MIDI-over-OSC:
http://www.symbolicsound.com/cgi-bin/bin/view/Learn/BidirectionalMIDIStreamsOverOSC
http://opensoundcontrol.org/spec-1_0

An interested party could pretty easily write a MIDIDeviceOSC class so we could at least support those without too much effort. Again, self-contained and there's plenty to work from with the existing MIDIDevice and MIDIDeviceHSS1394 classes.
