Sounds good so far. I set up an RM-AV3000 before. Still have it. Family hated it. The touch screen is definitely not something i'll be doing again, but I'm definitely not afraid to leave the harmony web setup thing behind.
Which brings me back to my question #1. If they don't remember states, then I'd need to find out how to discover whether or not there are discrete on, off, and input selects for the TV, receiver, and possibly the DVD recorder.
