Unfortunately these are not published. Really sorry you were jetlagged and missed the content. If you browse the agenda tool as we get Powerpoints they are published here and available under resources for the particular session.

I sent a message to PDC feedback e-mail.  I got a reply saying they will try to post some of the pre-confrerence videos.  They said they don't own some of the non-Microsoft content so some of the pre-conference sessions can't be posted.
