Grava, is the code name for a new set of tools from Microsoft’s Education Products Group that is designed to allow the education community to create and assemble materials that will increase discovery and allow learners to go at their own pace and learning style. "Grava" tools are scheduled for release in fall 2007.
Microsoft has a limited program of participation in their CTP evaluation program aimed at publishers, partner and software developers. CTP participation lets you communicate with the "Grava" team, access forums, get product announcements, and log bugs. Microsoft expects to initiate a wider CTP access program beginning in spring 2007.
