    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
