Subject: Re: [soa-rm-ra] resend: thoughts on management section (2)

Thanks for some interesting and thought-provoking issues, Ken,

As seems to happen with regularity, you bring up an issue, in this 
case simulation, just as I (and others I'm working with) are actually 
working on this. It just so happens that NIST's manufacturing 
division has a Modeling and Simulation group with whom we're working 
on some tests using their exercise control system (for emergency 
management scenarios). I can see where the capability could be used 
to test cross-boundary service lifecycles in specific SOA Ecosystems.

Of course, this would be particularly appropriate for EGov SOA, and, 
perhaps we could aim at September - October demonstrations? The next 
SOA for  EGov Conference is scheduled for September 6 and I'm working 
on a Collaborative Expedition Workshop for October 14, and like the 
back to back presentations last week, these could be efficiently 
combined. It might be worth including our RA work on this, though 
right now may not be the best time to discuss it. Apparently my 
inner-Murphy was displeased with me for pulling off the back to back 
presentation sessions so I went out and had myself a nice little 
bicycle accident last Friday. Relatively minor injuries, but 
definitely continues to get my attention.
