I'm learning that the Riot wasn't developed by the same team that did empeg / Rio Central / Rio Receiver, so I wouldn't be too surprised if it didn't run Linux. Also, I've since learned that it uses a wacko-proprietary USB connector, so getting a keyboard hooked in might be difficult (or at least require some kind of extension cable )

I read somewhere that it might be SDMI compatible, so there might not be any way to transfer files outside of Real Jukebox.
