In case the IETF is truly desperate: We could also rent out a major
university during the summer and stick everybody in dorm rooms - that
should be enough to discourage the tourists and evoke the roots of the
Internet :-) I'm sure OSU has classroom space for a few ten thousand
Then, there's always the Scout Jamboree option: build an Internet tent
city. I'd imagine Burning Man has more attendees than the IETF and it
seems to draw some of the same crowd.
