Here is the recording of the presentation I gave yesterday - enjoy: http://w.on24.com/r.htm?e=1001065&s=1&k=DAD5EBAFFBD67B61E8DAF6719D546A2A. Note that you will need to register with O'Reilly if you have not done so already. You also have the opportunity of seeing this live if you attend NCDevCon later this month.
