I did stumble across the fact that the "ALL in One" remotes used to have the ability to connect to serial ports. Some details can be found at:

The models known to have this feature are:
URC-2005 One For All 5 "Upgradable"
URC-2093 One For All 3 "One Call 3"
URC-2094 One For All 4 "One Call 4"
URC-4000 One For All 6
URC-4005 One For All 6 "Upgradable"
URC-4050 One For All 6 Hi-Fi "Upgradable"
URC-5000 One For All 12
URC-6050 One For All 8 Hi-Fi "Upgradable"
URC-6800 One For All "VCR Pro 8"
URC-6885 One For All "VCR Pro 4"
Sadly, these do not seem to be current model numbers. Perhaps the same feature is still available in current remotes or perhaps it was discontinued.
It would be a very handy feature to have. While I have written IR protocol code before, I cannot see why I should re-invent the wheel. I am perfectly happy writing the timers, state machines, and control functions for my particular needs and then leave the grunt work of actually coding the protocol to a dedicated chip or device.
