So I don't really have the time to write an app myself so I thought I would throw this idea out there. XM and Sirius both have web interfaces to allow online listening for their customers. Why not create an app that taps into their online streaming to effectively create a second satellite radio without the additional monthly fee? I think allot of people would pay about $10-$15 for it considering the cost of a portable satellite player, or with the use of an fm transmitter it could be used in your vehicle.
