NG2011/Technical meeting

work in progress

Status update/overview talks

Presenters should give a short high-level overview of the status and future plans of each topic, no longer than 5-10 minutes. The idea is to give everyone an overview of all ARC-related activities, not discuss technical details. Longer discussions will take place in later sessions.

May 11 Wednesday morning session
