Presentation Video : SL & VWs

When I do real life presentations at conference/workshops about SL / VWs I often show a 17 min video that I talk to (stops me rambling) then we get into discussions.
I've just put the video inworld on Int.Schs.Island at http://slurl.com/secondlife/International%20Schools%202/70/180/57

This is version 1 ... I plan to modify. (aren't we always)

No soundtrack as I usually talk to it live ... but may be of interest.
It is streaming into this location from www.blip.tv
