The UBR example is interesting because the four nodes do not always represent the same information, because of replication latency. So there are some times (during a latency period) when the same request gets different responses when applied to different nodes, revealing an internal behavior not fully expressed by the simple service URI.

So I find Frank's approach more satisfying in that respect, because it would allow me to describe this particular semantics in a way that cannot be fully accounted for by the service URI.

I suspect there are many Web services that might first look easily describable via a service URI but, when examined more carefully, reveal special application-specific semantics that cannot be adequately captured by the concept of service URI.
