TV GPS helps provide location indoors

Apparently TV isn't the soul sucking waste of time that my mother always told me it was. Redwood City, CA based Rosum Corporation has developed a TV-GPS chip that triangulates TV signals to provide location information indoors and is working with Trimble to bring it to the consumer. While this isn't in any way "new" news, it is the first time that I have seen or heard about it. Popular Science has a good overview article about the technology. If this works as stated and can be produced cheaply and in a small enough package, this seems like a great way to fill some of the location holes in urban areas.
