Link Harvest: Problems for Lightsquared

I am a big fan of Lightsquared, which attempts to use satellite frequencies through terrestrial delivery systems for broadband (an FCC rule called the "ancillary terrestrial component or ATC). Unfortunately, the sheer cost of building a national network may prove prohibitive even when you don't have to get spectrum access at auction.
