John Sheehan, Architect of Microsoft's AppVirt (SoftGrid) technology, spends some time with me digging (deeply) into the architecture and engineering of the application virtualization technology he and team create. A few months ago John joined us for a Going Deep on application virtualization and you asked for more (and you asked for us to go deeper - John only scratchd the surface last time we spoke). Well, here you go, Niners. Deep AppVirt. This is whiteboard-heavy and John's mic'd so the sound quality is exceptional.
