I found information on another board that wifi service is being offered in the common areas of several hotels at WDW. It doesn't appear that you have to be a guest of the hotel to access the network. There is a fee - either per hour or per day - but you pay by credit card to a third party (not Disney) when you log on for the first time. The Contemporary, Coronado Springs, Grand Floridian and Boardwalk Resort are on the list.
Personally, I'd rather take a boat ride to the Contemporary and log on to a wifi broadband connection for $5.00 than a bus to the Outpost to dial in to a 56k max line for $.75.
Who knows, maybe wifi will be coming to FW soon!
