use cases in the "Introduction to OSC" page

hi,

the "Introduction to OSC" page is not really healpful to me. Could someone add some use cases there that illustrate the scope of OSC.

I work one a music composer and add features to control effects externaly (e.g. via joystick). Now I wonder if I could make a ui client on a handheld and offer controls there that can be linked to the effect-parameters on the host. OSC sounds like the right protocol to comunicate. It seems that people have thought about discovering clients via Bonjour/Avahi. Now I wonder it the host (composer) could negotiate needed ui controls with the client (handheld). E.g. suppose I show the mixer on the client, can I tell the client how many channels it needs to show (and give it the labels).
