If you're a frequent business traveller, I would imagine that you've been faced with the daunting task of gaining internet access in airports and other public areas. Yes, I know that you can use your cell phone as a wireless modem, but the average user is likely ill-equipped, and unaware of how to get it working correctly.
Many airports have adopted a pay-for-use Wi-Fi, through partnerships with larger companies. Everyone wants a piece of the action for a service that really costs little to maintain. Airports aren't the only places that are charging for Wi-Fi, the local bookstores(ie Borders, Barnes&Nobles, etc).
So, I'm estatic to learn that some municipalities are lobbying for freee Wi-Fi. In fact, many politicians have made it point to place it on their campaign agenda.

Yes! As a frequent traveler I'm apaled when I have a layover and can't get onto the internet. I actually schedule my flights around airports who have wireless access. Some airports like Vienna's offer it for free. Sigh unfortunately I can't avoid Dulles Int'l which hasn't reached the 21st century yet.
I don't think that Dulles is alone. LGA is another.
Ahh but road warriors do not fear, this list might be useful to you.
