OSC is connectionless, at least if the implementation uses udp as the
transport-protocol (which most do). So there is no real way to even return
values. Most apps send return-values to the host/port the query came from,
but if that fails or is not handled (as the current state of ofqf...),
nothing really happens.
Thats already quite a problem, introspection/interrogation is totally up to
the dev writing the app you want to control.

I would propose some basic "/introspect" to send back some kind of textual
representation of the tree of options that is handled by the app. But its up
to every programmer to implement this. And then we still have to negotiate on
a format for the answer... (/me is voting for some xml: <path
name="bla"><path name="first" ><argument type="int" /><argument
type="string" /></path></path> :)

Have a nice week,

Arnold
