Wireless broadband hits Greensboro this year

A friend pointed me to Clearwire a couple of days ago. They currently offer wireless broadband for much of the West Coast and a few other areas of the United States, but what excited me was that they plan to start offering service in Greensboro sometime this year. I wonder when Raleigh might get coverage?

Clearwire uses cell towers to provide Internet service to devices throughout metropolitan areas. This sounds very similar to what Nextel tried a year or so ago. Does anyone else have news on other wireless service providers who may be setting up camp in North Carolina soon?
