XML Web Services & Security
Handy writes "Web Services (SOAP, .net, WSDL ? , UDDI ? ) create an even greater need for robust security. Exposed interfaces and fragmented administration coupled with a need for app-level security points to a greater need for a centralized managed security services model."

A whois search also reveals that xwss.org and westbridgetech.com belong to the same people.
And to top it all off Westbridge sells an XML message server. Just what you need to implement all the good stuff talked about in the article.
