The Nexus *card* and the driver support two protocols: RC5 and RCMM.
The keymap file selects which protocol to be used.

The ir *receiver* supplied with the Nexus is too slow for RCMM.
It can be used for RC5 only.

If you build your own receiver using a better ir receiver chip (e.g. 
TSOP1136), and connect it to the Nexus card, you can use RCMM.

The remote control plugin itself is not restricted to any protocol.
(Of course, it requires a driver which provides the key codes.)

If you want to use different protocols at the same time or other 
protocols than RC5/RCMM, you may use lirc with a home-brew receiver (or 
a similar device).
