I think USDTV is a good service for metropolitian areas where cable can't be installed. In the markets USDTV is located the "cable" channels don't come over major network affiliates.
I see nothing wrong with the service, if stations aren't going to use the space. Look at it this way. We have a full power station airing America's Store 24/7 and a local religious station. These stations will probably never transmit HDTV. So what would be so wrong with these stations airing USDTV programming? Also is it so terribly bad for a PBS station to air USDTV. NCE stations around the country are in desparate need for money. Analog FM and TV stations rent out bandwidth for data services and paging systems all the time without the public complaining that the TV stations aren't using SAP or that the FM stations are no longer providing radio reading services.
As for stations pimping out their bandwidth. They don't get a free ride. Stations must pay 5% of the GROSS income from ancilliary services on their Digital stations to the Federal Government. In addition, stations multicasting must increase the number of hours of Instructional/Educational programming for children and the number of hours of Public Affairs programming. If the multicasts are scrambled (as is the case of USDTV) the additional hours of programming must be aired on their main unscrambled channel.
So as you see USDTV can be a "good thing". The government gets some badly needed cash, children get more educational programming, and adults get more public affairs programming.
