Rackspace will host this one, so there will be lots of room. If we can find some good speakers, we'll have them. Otherwise we'll appoint a Panel of Experts to answer any and all questions about ES (performance, sql-->es, others - please comment!) This meetup is very young, so we will adjust the format as we get more input, but the basic plan is to have a smaller, very informal meetup every two weeks, and a large one - Rackspace! - every 6.
