I recently bought 2 O2 jogglers, and used Squeezeplay OS as a base to add Orbiter to it. Now I added 5 more...
atm it is a pure Orbiter, which works fast, needs manual configuration, doesn't do a screen saver, but is okay for me.
btw: The joggler uses 7W of power, and you can use some Level One 1201 PoE Splitter to power it via a PoE switch. It is important to note, that wall mounting isn't straight forward, as you need a good heatsink for it.
