I am designing a system that will use prodigy to run a/v distro throughout a home. Audio is no issue. Distro video will require a bit more programming, but I am confident that I can manage.
The issue is controlling the remote TVs. Since Crestron is all RF, I need an emitter or serial on each TV.

So, the Global Cache iTach line looks great for this. The module that exists is only in Simple. It doesn't look like it would be very easy to convert like a basic serial module.

Is there a SystemBuilder module out there already?

Is there another option that I should consider?

Having a control box next to the remote TV is key in this situation.
