Microsoft TechEd 2008, Day 3, 10:00

The first session of the day was Deploying and Migrating OCS Server 2007 Release 2.

There's a few feature changes between 2007 and Release 2 - which is in Release Candidate at the moment but due out in February - such as dial-in audio conferencing to an OCS voice chat, better Windows Mobile and Blackberry integration and such.

However, the architecture changes to support this mean that, like Exchange 2007, it requires 64 bit Windows under the hood. It also requires AD schema changes.
