This is the moment so many of you waited for so eagerly: WSE2 has been released! The freshest WS-* implementations, including the OASIS standards on security and the latest upgrades to WS-Trust and WS-SecureConversation, ready for you to use in your production project. Nice evidence of the power of WSE2 (and Information Bridge Framework!) can be found here; for a fine drill down on WST & WSSC from Martin Gudgin see there.
Last but not least, take a look at what partners and customers has to say about WSE2: there's some Italian customer I may have heard of ;-)
