While were about it I'l plug liblo, http://plugin.org.uk/liblo/ a C OSC
implementation thats designed for people on the same lazyness wavelength
as me. It makes it as easy as I could to do OSC things, eg:

	lo_address t = lo_address_new("localhost", "7770");
	lo_send(t, "/foo/bar", "ff", 5.0f, 23.0f);

Making OSC servers is slightly more work, but not hard. The latest version
handles scheduling on the server side (for incoming timestamped message
bundles) and all kinds of things.
