Multiple physical resolutions of a single logical address should be done by an external resolving server (something like DNS). Having the addressing mechanism do resolution from logical to physical means every client in the world would have to keep a database of all the physical resolutions of a logical address and continuously update it to avoid stale entities. It might not be a big problem for small number of resolutions, but when the number of services explode, that addressing mechanism will not scale.

That is no different than carrying the other addresses in Metadat, thus carrying equivalent data in two different locations. That doesn't make alot of sense to me and I think it will result in the same information being carried in different locations by different profiles as each profile makes up their own alternative location for the equivalent data. I don't understand what you mean by "duping the wsa:address for EPRs everywhere." We aren't talking about duping anything. We are talking about carrying multiple physical endpoints in a single EPR describing a single logical endpoint. I think that it is very appropriate for an addressing specification to deal with the fact that a logical endpoint *may* have multiple physical endpoints. Conor
