There's something similar in Canada, which has been operational for several years. Although it may differ in its technical implementation, it appears to do the same things. The service, at least in the Toronto area, is called Look TV. See http://www.look.ca/e/index.html for details. They use a line-of-sight scheme and a small, triangular-shaped "dish" to receive the signal. It's used either in homes or multi-unit dwellings (e.g. high rises).
The TV side is new to the US. I have a broadband Internet by Sprint that is line-of-sight within 35 miles of the transmitter. Speeds, at best, have been T-3 when the net is less busy, like Sunday morninigs. The dish is 12" square. Weather has not affected reception. Sprint is no longer selling this as a new service...but maintaining current clients. Makes me a little nervous. I can't get internet via cable or DSL where I am; so MMDS is appealing.
