In case this thread turns into a referendum on the merits of WS-Addressing, I would like to point out that that the Basic Execution Service (BES) spec incorporates EPRs into its interface. 

 

So, if PGI has apsirations to discuss anything that resembles BES, support for WS-Addressing would be a Good Idea if for no other other reason that to not have to completely re-invent the BES wheel (again).
