There is an important synergy between Integration (web services) and Security. So I also (try to) follow a bit what is going on in the world of identity mgt, security and so on (and I'm simply interested in security).
One presentation that I've been listening to and really appreciated was from Dick Hardt, CEO of SXIP. Dick explains how in an Identity 2.0 world (and Web 2.0 ?), the user will become central in future generations of identity management solutions.
But what strikes more is the way in which he uses PowerPoint to explain and entertain. Very, very well done!
