The Four Points turns out to be a reasonably nice mid-range hotel with free (I think?) broadband in the room. There must be a few OSCON people staying here because I can currently detect two different WiFi networks that have nothing to do with the hotel.
Totally shattered after getting the red eye from Heathrow straight through, via Washington D.C., to Portland.
However the worst of it was the 2 hours it took me to get through immigration, customs and baggage recheck. Which was followed by another half and hour trying to go through security (we were still air side, so why did we have to go through security again?). I almost missed my connecting flight, and I wasn't alone, several people did infact miss their flights. Apparently this is pretty normal for Dulles, so I think I'll strike it from my list of "aiports to enter the U.S." for the future.
