The reason I'm asking is for controlling jamin remotely. JAMin already has
OSC functionality after all Steve Harris wrote liblo ;-)

My problem is figuring out how to test JAMin to make sure I haven't broken
anything with any of my recent updates. Specifically I added a "Daemon" or
"Headless" mode and I would like to check that the controls are all still
working. In addition it would be nice to be able to control the JAMin
daemon from a remote machine. So the the two issues are how to connect to
a server app and also how to do that from a remote machine.

it looks like oscsend is going to be the way to go for now.

I'm tempted to spend some time on a python/clutter generic osc controller
app but if you have already started on that it might not be necessary. I'm
also thinking of adding support for OSC send to JAMin (if it is not
already there) so it can be a remote controller for the JAMin daemon. Call
it "controller" mode...
