In response to this, I'd like to point out that the set of people
willing to work on workflows and the set working on security are not the
same (e.g. I don't personally want to work on security standardization!)
so saying that we should drop dealing with one in favour of the other
isn't really going to work.

I suspect that the most valuable thing at the workflow level would be if
we had some common way of describing workflows in a way that is relevant
for grids. I suspect that the best way of couching this is to ask "what
is the best way of describing an abstract workflow to a workflow
enactment engine", such that something like JSDL documents form
components of the workflow request. While a BPEL profile could be used
for this, I suspect that it's not at the right level; too much is about
the messages sent to the services, and not enough is about the
activities triggered in response to said messages.
