We are currently working on setting up screencasts for a few select presentations at the OpenForce '07 conference in Las Vegas.  We are currently not sure how those will be offered to the community.  In general we will not be providing screencasts for the complete conference since it would then be competing directly against the conference.  While we understand that everyone may not be able to attend the conferences, we also have to sensitive to the fact that our conference partners, sponsors and vendors have spent a lot of money to run, attend and advertise at the conference and offering webcasts of the events would be counterproductive to our efforts.
