Since we have a lot of people coming from the same institutions and locations, it would be very “green” of us to carpool.
I am also working on a “green” way for others to participate by using ustream for live broadcasting of the sessions and twitter as a backchannel. I am more of a web 2.0 n00b, but together, I’m sure, we’ll get it figured out.
I appreciate the comments so far about what people want to discuss. Remember, we will be determining the topics for the discussions starting at 9am, so, if you have a hot topic you want to discuss, it couldn’t hurt to post it here and then be there on time 
to add it to the list of potential topics.
I’ll keep you all posted on our 2.0 progress (hashtags, URLs, etc.)
