If you missed the webinar we did with Virtual Iron earlier this week, there's an archived version available here. It's a 30min webex presentation with the first half explaining the virtualization piece (specifically Virtual Iron in this case) and the second half talking about the JumpBox piece with a full walk-through of the process setting up the Alfresco JumpBox start to finish. Big thanks to Chris Barclay and the folks at Virtual Iron for inviting us to participate.
