If there's a desire to trust information garnered from the Internet Routing Registry (eg. RADB, RIPE), it would seem that one would like a way to verify the server responding to queries.
At this time, I think verification and sanity-checking of the data that goes into the IRR is more important than that which comes out of it. There is a plethora of stale registrations, entities who don't register (*cough*701*cough*), and at least one entity which is robo-proxy-registering routes "in the wild" (due to the folks who don't register.) I'ld love to see the first cleaned up (including others who have registered chunks of your address space with their own maintainer, making it tough to delete (much like the old problem of others creating/referencing DNS servers making it impossible to have them deleted.) The second group annoy me to no end, both in the customer and in the peer variety. The third is somewhat annoying since it can mask leaks from the folks who _do_ register, and doesn't really solve #2.
