Looks like the IGI book " Multi-User Virtual Environments for the Classroom: Practical Approaches to Teaching in Virtual Worlds" that we wrote a PIVOTE chapter for is out. The chapter explores the background to authoring learning systems in virtual worlds, why we developed PIVOTE, the PIVOTE architecture and an example use case, and a couple of case studies from institutions using PIVOTE. Rest of the book should be good reading too. Enjoy!
