The bad news is that it's a wired connection, not wireless, so other people in the room won't be able to participate as much as we might have liked (although they can send Twitter messages through their own wireless devices). Had I known, I could have brought my small 5-port hub and extra cables so that a few other people could join the event on the spot as well.
Cascade 10 is half of the room where we're doing Match Game SF tonight, so we should be able to test the internet connectivity this evening. In case of last-minute technical failure, an alternative location (where the free lobby wi-fi reaches) is the foyer outside the Evergreen Meeting Rooms. If you're at Norwescon, look for me in my WSFS uniform on Sunday.
