Here is what I wrote:

This specification closes a huge gap in the SOA stack. As people move to SOA, the "location" of a business entity will become "fuzzy". It is likely that even the theoretical grounds of federation will not be enough to address this issue, well here is a very elegant solution. "With cross-domain applications comes another complex problem: the need to share instances of the same data across multiple domains, directories, databases, and applications. There are many facets to this challenge: identification, authentication, authorization, mediation, and synchronization; all problems that were minimized on the Web because it dealt primarily with presentation of data rather than interchange of data."
