OK, here's my Rube Goldberg suggestion for controlling the Rio Receiver via PC: Obtain a PC to IR sending device; learn the Rio remote control codes; write a program that compiles the music database from the music server using the known protocol; have said program "push" the remote control search keys (in Rio documentation) to type out the user's requested album/song/etc based on the text info from the database. I am certain that this can be done for anyone putting in the effort.
