Nope. Do to the lack of docs on programming the api you haven't seen
anything done.

No root!!! If the RRM is design right you don't need root. Well except for
the master node (SGI terminology) that controls the global state. For
example root would only change the resolution since this can affect every
client using the accel engine. Even that I think doesn't have to be root.

That sucks :-(
