Is XM/Sirius a threat to internet radio?

[Mike413]

It's unfortunate that more casual fans don't look to the internet to listen to prog and in a way it seems dumb to pay to listen to something that you can hear for free(internet radio). However, at the moment you can't listen to the internet radio in your car or anywhere other than in front of your computer so satellite radio does have some advantages. I suspect as long as internet radio exists there will be plenty of people to listen to it so I feel the real threat is can the powers that be ban internet radio as opposed to not having enough prog fans to listen to it.
