Perhaps useful input to BES discussion

[Ian Foster]

Dear All:

I am sending this draft document in case it is relevant to the OGSA-WG 
and/or BES discussions.

In this document, I use a simple example (a skeleton execution service) to 
compare and contrast four approaches to representing state, namely WSRF, 
WS-Transfer, REST, and "state id."

I haven't sent this earlier because I'd hoped to integrate numerous 
comments that I've received from Savas and others. I hope to do so in the 
next week or two, but perhaps this draft is still of interest.

Regards -- Ian.
