I gave a presentation on WSE2 at the local .NET users group on Tuesday. In the face of failing health I was able to give (what I thought) was a reasonable talk. I think the coolness of WSE helped me rise to the occasion. I should have practiced the talking parts more (as I wandered a fair bit), but the code demos worked and I was in the ball-park of the alotted time. Local remoting advocate Richard Mason was kind enough not to lay into me too much in the Q & A part at the end, however he did ask one question regarding similarities between the Messaging part of WSE and remoting which I am looking into. Greg Low also gave a talk on MSDE, re-distributing it, and changes between MSDE and SQL Express 2005.
Update: My slides from the presentation are available here
