Thanks to this thread I just dodged a bullet and avoided buying a URC remote system as part of a larger speaker purchase I was making. After reading this thread I asked my authorized retailer if they could provide me with the software, and they said that URC prevented them from doing so.

I then went to a second local retailer and asked them the same thing, and they said that they choose not to give out the software (that the program they make for you is their IP so they choose to protect it and not share it with you.)

I'm all for getting a full service install and having my vendor set it up at first (since I'm also paying them a fortune to fish wires, mount my TV, etc.)-- but I'm not willing to make an investment in equipment that could end up worthless if I am locked out of making changes after changing some of my gear. But that's just my opinion, and I'll vote with my pocketbook.
