I think the current OUI getter code (make-manuf) needs to change anyway - it currently gets the 22-bit OUIs and Individual Address Blocks (IABs) from IEEE's website, but does not get the OUI-36 listing that's been used since 2007 (http://standards.ieee.org/develop/regauth/oui36/oui36.txt).
IABs and OUI-36 are very similar, but have a different reserved OUI prefix and are thus a separate number space. Technically an IAB is not an "OUI", and can only be used for EUI-48 addresses (i.e., 48-bit MAC addresses). On the other hand an OUI-36 can be used for other things: an EUI-64, CDI, and as an extended OUI - although in practice my guess is people do the same thing with IABs anyway. The IEEE is considering merging the two into one registry, but they'll still have the current numbers/prefixes - for wireshark this just means that the URL to get the listings may change.
Also, the IEEE is proposing to create OUI-26, OUI-28, and CompanyID registries.
