According to the definitions in RFC 4084, the only one that applies to an
ISP with lying resolvers as described in this draft is "web connectivity".
This could be extended to other protocols, but that depends on explicit
support from the landing server. In some respects the service model
described in the draft is less than web connectivity, because it doesn't
support https.
