There are a few features that can be used to distinguish remotes: 1. Carrier freq 2. Protocol (NEC, Sony, JVC, RC-5...) 3. Protocol variant (NEC original, NEC with extended addresses, RC-5, RC-5 with exteneded commands, RC-6 Mode 0, RC-6 Mode 6B, ...) 4. System # or Address sent by the remote (16 bits max, I think) 5. Set of possible Commands or Information words sent from the remote. 6. Pulse width deviation from standard (mean, variance) 1, 5, and 6 are really a sort of "fingerprint" and likely not worth the effort, even if you have hardware that can measure things with some accuracy.
