I just finished a prototype IR remote for the RS1500. It controls play, FF, REW, pause, stop, REC. It could also be set up to control reverse on an RS1700, and I suspect I could rig it to control the power switch on-off.
It's really fun to sit back and cue up a song from my listening chair. I'll work up a proper housing (my prototype receiver is in a little hinged top wood box sitting on top of the RS1500) and some pricing.
