That's an awfully good point. One thing this discussion has clarified for
me is that "Web Services" cover an awful lot of application territory, from
behind the firewall EAI, over-the-web aggregation such as Amy Lewis
described, to the wireless device scenarios I usually bring up. Clearly
one set of best practices doesn't cover all, and I suspect that the
granularity issue is much like the synchronous/asych issue -- the better
your connections, the fatter your clients, and the faster your back-ends,
the more viable "SOAP as just another RPC mechanism" is.
I'd just remind people of the converse -- the worse your connections, the
thinner your clients, and the uglier the back-end processing, the more
important it is to ratchet up the granularity and to consider asynch
messaging protocols, pipeline processing models, the "spaces"
coordination model, and so on.
