Introduction

Roundtable XX took place on February 9-11, 2011, hosted by the University of California, Berkeley, in Berkeley, California. The event was attended by 30 people from 17 organizations. The CalConnect Interoperability Test Event was held immediately prior to the Roundtable on February 7-9. Thirteen people from 6 organizations were present onsite, and 3 organizations and 3 people partipated remotely.

The Roundtable was dedicated to technical committee sessions, and informal discussions and networking, with an all-hands Plenary meeting as the last item on Friday afternoon. The Technical Committee sessions were as usual organized sequentially, without competing parallel sessions, as is our standard practice to allow all attendees who wished to be involved in the discussions of each Technical Committee the opportunity to do so.
