Liblo comes with "oscsend", a command line tool to send an OSC message
to a specified listener. That's good for testing. Also "oscdump", a
server that just echoes incoming OSC requests to stdout. A very useful
pair.

The way I implemented learning is to add a default handler to my created
OSC server, take the next incoming message, pick the "path" out of it,
and then add a handler for THAT in place of the default. It's possible
to get in a race if you are trying to learn with lots of OSC data flying
around but that's the user's issue :)

I think OSC was designed with the idea that the servers would define the
"name space" of paths and you would build a client map to send controls
to the proper destination. It looks more like it's really working the
other direction, where the clients/controllers define the paths they are
going to send, and the server is responsible for learning the mappings.

Thanks,
