Microsoft has arranged with Acxess, a Microsoft Partner, to host a Virtual Learning Gateway Environment that institutions can use to test drive the product in a deployed scenario. This is by far the easiest way to experience a deployed K12 MOSS environment, and the site even includes a "Saved State" feature so your staff can return to the site, run the demo, and save any changes they make to it and reuse it as they like.
