Looking at the programming box that you guys are talking about, do you think it is possible that the manufacturer of these remotes has a similar thing to upgrade their remotes? From a manufacturing point of view, it would make it easy to upgrade the remotes.

I am not much of a software person but I could make a PCB layout from the schematic (for the programming box) that would make it easier to build those boxes. The only problem would be that it is to expensive for me to fabricate the the actual PCBs.

I can have a layout in a couple of days if someone is interested!
