The best rio client at the time XPL started was rioplay. I don't know if it could be done for tRIO?
The slimserver also has XPL support.


Hmm. Does the client really need to support XPL - I woiuld assume the interaction would mostly be at the server level?
I do want to be able to inject announcements/phone rings into the music stream, as well as turn music on/off from my home control system, but I also need the synchronizing and other features of tRio....
