In reply to David Chao.

Great idea, David. Yes, TelePresence enabled a discussion that would've not been possible in a physical way (imagine a table with 46 people talking seamlessly!). We pushed the TelePresence to its boundaries, as we connected 48 HD screens together (many rooms having 3 screens). And we used Cisco Jabber throughout the session in order to gather the comments towards the speakers, which made the Q&A sessions very effective. I will follow your advise and write a post on the lessons learned from a collaboration perspective.
