Even while sitting at Gnomedex, (on a Saturday), I have to keep up with my day job.  This looks like a great way to view the slides and watch the sessions from Tech-Ed 2005 a month ago.  http://microsoft.sitestream.com/teched2005/  

Tech-Ed Sweetness...  (Find the BizTalk Stuff in the "Connected Systems" track)...

Update: This site now requires a password - so it is now for attendees only.  (Which I wasn't this year...  Shucks).
