See RFC 2168 and 2169 (if memory serves, I'm offline at the moment). The first defines a new resource record, NAPTR, which has been implemented in BIND for a couple of years now. It is used for finding one or more 'resolvers'. The second RFC defines a trivial protocol for communicating with resolvers using HTTP. Together, they will let URNs in a new "foo" namespace be mapped to a URL. The bottleneck here is that for the "foo" namespace you need to get the domain name "foo.urn.net" and put the NAPTR resource record there. The only way to get that domain is to fill out the application form the IETF's URN WG has been defining. It doesn't cost anything right now, and there are no plans to charge for such names that I know of, but its safe to see the registration procedure is not a smooth and polished process. (The purpose of the procedure is to prevent cyber-squatting on URN namespace identifiers, and to insulate the owner of the urn.net domain from lawsuits if he had to make the call on whether or not to register "foo").
