I talked with several people @GGF13.

1)If you loook at the two layered picture of Agreeement Services and the 
lower level, Real services (Such as Job submission etc), My 
understanding is BES has to deal with the Serive layer beneath the 
Agreement Factory layer.

2)On the other hand EMS has to look into what is the relationship 
between the Service Layer and the Agreement Layer.

Eg. Is the Job defined first in the Service Layer and an Agreement Layer 
   has to encompass this or, Is the Job defined between the Service 
Layer and the Agreement layer as a result of the CreateAgreement Operation.

There *ARE* open questions as these which someone has to address...

 From my undersatnding, EMS had been waiting for WS-Ag to get fixed.

I've also heard several semntimets from other projects...

Actually as I said before, several WGs /  projects are really waiting 
for output from GRAAP-WG.
