Finally!
I've arrived at the Kalahari resort for CodeMash and after about 20 minutes of fiddling (and moving around the room), I finally found a spot that will hold on to a WiFi connection -- albeit slowly: 5mb transmit and 6mb receive. At least I can get my RSS feeds downloaded!
Let's hope it's a little better down at the convention center where I'll be spending all of my time tomorrow.
