Sorry for not replying sooner, but this is just a short note to say that
there's a fair chance that it will not be straight JSDL that comes out
of the EPS, but rather something based on WS-Agreement. I'm still
looking through the details, but I think it's possible to build a
protocol with sensible semantics on top of WSAg if you combine some of
the more unusual configurations (I think you need pending agreements and
to place the BES in the role of agreement initiator, in case you're
interested).

Logging this to OGSA-RSS as well. The details of this aspect of the
discussion belong there.

Donal.
