In a related article published here in eweek, a quote from the article says "The companies' cooperation will soon give developers freedom to work with Web services partners using Microsoft's Windows Communication Foundation (formerly "Indigo") or JAX-WSA (Java API for XML Web Services Addressing)."

Although I fully agree with Peter that this cooperation between the two companies will provide flexibility to work with either of the framework. But here WCF is incorrectly compared to JAX-WSA. The latter provides an API to enable WS-Addressing support in Java platform and is just one of the multiple specifications supported by WSIT. Instead WCF should be correctly compared to WSIT. I've already emailed a correction to the editor and hopefully will hear back soon.
