I think your system is exactly the opposite of what I want, but I cannot tell from what I have read on your site. In my household, I have several people each of whom has an iPhone and/or and iPad. I also have several rooms. All the AV gear is controllable using IP or RS-232. What I want is an application that works with a stateful server (like the 890 Pro was), so that when a user launches the application it is in the correct state for the room ([i]e.g.[/i] the volume shows the current volume level, the correct TiVo is selected for control, and so on). Without a stateful server, I am not sure how one can accomplish my requirement of allowing multiple iOS devices to control a common set of AV gear.
