Besides being an RTI dealer I use them in my own home, but a less complicated approach for you would be to use URC's MX-6000. First of all, Mirage liscence is already included in your purchase price of your remote. The only RTI remote I would ever think about using for this application is the T4. The T4 can be slow and while there seems to be a new flat panel coming down the pike, it may take awhile to get here. I just did a house with an MX-6000, lighting control and using Mirage and a PSX-2 and the client was extremely happy. That would be your most cost effective approach as well. Autonomic on RTI could cose you 1K alone minus any programing costs.
