Does Universal Remote make any 2-Way Communicating Remotes? I don't think so, but I wanted to makes sure... It doesn't look like the MSC400 does 2-Way RS232, and seeing that is the closed thing URC comes to a control processor, I assume there is no 2 way communications on any of their remotes.... Wondering if anyone out there knows if there is something coming down the pipe from Universal Remote in terms of 2-way...
