I'm exhausted.  I have just completed WIN325 - Microsoft and Interoperability, which was great fun, but two sessions in one day is tiring.  The session was well attended, and David's demo was a hit (from the initial evaluations). 

I'm currently sitting in Ted Neward's session (DEV 381 - .NET and J2EE - Strategies for Interoperability).  He's ditched Powerpoint in favor of notepad...  I'm starting to get worried... <g>
