The biggest problem with a scheme like this isn't the IR codes themselves. A Pronto CCF file would be easy to create and would let almost anybody with a computer-programmed remote (Pronto and Universal can both use the CCF file, and Logitech/Harmony could add it to their online database). I would assume that Niles' Intellicontrol would also handle CCF's easily enough, as would similar centralized control systems like Crestron. The problem is providing them to
all consumers in a useful form, because this scheme would be an "all or nothing" sort of affair.
This page lists pricing for the Intellicontrol as being $3000 on up. A more basic system may be possible, but that's still a major investment. This scheme would have to work with the remote that is shipped with the processor, and without need for a custom installer to configure any of it.
There really has to be a pre-defined limit to the number of inputs that are available, at least at the price point that Outlaw focuses on. The concept of highly-definable inputs appeals to me (as I've said, it's one of the things that I've really enjoyed about the 990), and I think that there are several input types that deserve this sort of assignability (coaxial/optical, component, DVI/HDMI) along with editable input names. Beyond that, an unlimited supply of inputs isn't going to be practically feasible for an Outlaw processor for a long time, if ever.
