It's certainly very desirable that we end up with a single common model!

We have the ESI model, that reflects experience in GRAM and Unicore; the BES model; and the SAGA model.

And I would encourage BES to pick up this model as well. I was going to make
this comment on the BES document, if it ever would show up in public
