Lightning Debates at NANOG 51

Folks, I've been tempted by the NANOG PC into trying to run some "Lightning Debates" at NANOG 51 in Miami. The idea, similar to lighting talks, is a 30 minute session, covering 3 debate topics, 10 minutes each. Each person would get 5 minutes to argue their side of the issue. Some ideas so far: UPS Systems: Battery vs. Flywheel Cooling: Raised floor vs. Underfloor Power: AC vs. DC Ethernet: 40GE vs. 100GE Optics: XFP vs. SFP+ Address Families: IPv4 vs. IPv6 I'm soliciting panelists, and ideas. Please let me know if you're interested in participating in what will hopefully be a unique and exciting session. Best, Tom -- Tom Daly http://dyn.com/
