I think Worldcom even owned the code for at least two working implementations at one time or another :-) Essentially a route registry is a way to tell everyone "only listen to this route/prefix from me." But if every ISP runs their own route registry, you end up with the same problem with an additional level of indirection. C&W's route registry says their route, Level 3's route registry says their route, Verio's route registry says their route. Etc with Merit, ARIN, RIPE. However, it is a step forward to get the informaton in a common format which can be shared/munged/checked/etc. The route vectors in BGP are very information limited. RPSL/rWHOIS has the opportunity to provide more context.
