(Consuming) Interchangeable WCF and JAX-WS services

WCF

I have N quantity of "clients", and each one has to implement a web service for my .Net app to consume. I dont want to add a service reference for each client because they can change at any moment, as well as the URLs, so I store the URLs on a database and dinamycally create the endpoint depending on which client I want to access.

I was wondering if I have to force my clients to write the same type of services(either WCF or JAX-WS) or I can still connect to one or another without writing some kind of conditional logic.

ie. If JAX-WS then "do this" ELSE IF WCF "do other stuff"

Also I was wondering if adding WS-*(wshttpbinding) security would add more complexity for the interoperability(or interchangeability) of the two technologies.

Any comments about this approach would be greatly appreciated.
