This is great, and I am happy Microsoft has put forth a great product to fulfill collaborative white boarding on their platform. Microsoft has been supporting of digital convas technology for a long time, which was finally streamline in the inkcanvas control in WPF over a decade ago.

This solution from Microsoft has been floating around the education sector for sometime already by Dyknow, a small company HQ'd in Indiana. Curious if this firm's tech was bought out or just copied.
