Since the Ubuntu UK podcast was heavily involved with OggCamp: http://oggcamp.org/2009/start, I wondered if any of the the Chicago people would be interested in bringing them over. We'd need some pretty hefty sponsorship money to fly everybody over. I'm going to try to get Dan and Fab over of Linux Outlaws over.
I have decent venue connections in Milwaukee, but not in Chicago. I think it'll be easier for people from the UK (and elsewhere in the states) to come to the event if it's in Chicago.
