Yeah, no need to reinvent OSC.
In fact why not retain the OSC syntax for in-process GUIs too. Replace TCP
with something more direct, like simple function calls into the host. That
way both remote and local GUIs become essentially the same thing (with
different 'transport' mechanisms).
Running a GUI remotely then becomes a case of inserting a TCP wrapper
between GUI and Host. The plugin dosn't need to know.
OSC...

/voice/3/freq, its type string might indicate that there is a
single floating-point argument, and the argument might be
261.62"
