Re: SOAP/XML Protocol and filtering, etc.

Two firewall community lists you might try are..

  firewall-wizards(_at_)nfr(_dot_)com  <http://www.nfr.com/firewall-wizards/>

  firewalls(_at_)Lists(_dot_)GNAC(_dot_)NET  <http://lists.gnac.net/firewalls/>


There was a short thread on the latter list (around the first of this year) 
along similar lines to your query. The thread was entitled..

  "new" protocols vs. firewalls & firewall adminis{trators|tration} ?
