Oh yeah - sorry, wrong list.  Ok, to www-ws it goes...

Useful, most definitely, but I firmly believe we should accommodate the
developments in WS standards, but not be constrained by them.  For
example, I recently had a discussion with someone who had made the
assumption that all messages between WSDL clients would be strongly
typed, and formatted in XML (which isn't always the case - consider http
bindings, for instance).

We should harness what WS give us, but... well I'm about to repeat what
I said above.  Also, I'm seriously concerned that we could risk
re-inventing the wheel, by ignoring work in other service-anaolgous
research fields (e.g. DAI, Grid, Multi-Agents etc).
