In a related note I just came across earlier today:

SAN FRANCISCO- SoftNet Systems, which provides fast Web connections over cable-TV lines, said it started a venture with CMGI and Compaq Computer to sell wireless Internet service in airports and hotels.

SoftNet and its partners will invest $100 million to start SoftNet Zone, targeting business travelers throughout the United States. As part of the plan, SoftNet said it will pay $48 million in stock and cash to acquire closely held Laptop Lane, which sells Internet access in 12 U.S. airports.

The company, based here, said it's working with Cisco Systems, the maker of computer networking equipment, and cell phone maker Nokia to sell Web service to travelers for about 50 cents a minute. SoftNet wants to take advantage of the surging number of people going online using laptops, cell phones and other wireless devices.
