There might be IPv6 in the night venue, where we all go at 11:00pm if we don't go somewhere else. I don't know because I've not taken my computer to the night venue so far as I've been heading off to bed mostly (i.e. except last night when we had the wine & cheese "BoF" there) fairly soon after 11:00pm.

Maybe someone will set up a tunnel in the day venue.
