I recently spent two weeks in Prague. I worked face-to-face with some of our WSIT engineers located there, some I had never met in person. I also participated in Sun Tech Days where I gave a overview of JAX-WS and WSIT. A number of people have asked for the slides. You can find them (along with other slides from the Prague event) here. Look for my presentation titled "JAX-WS and Tangoing with .NET (WSIT)". You can also find a copy of my presentation on The GlassFish Wiki on the presentations page.
