Is XM/Sirius a threat to internet radio?

[RogorMortis]

Vax has got the core of the music movement. Not only would I need to gear up to listen to satellite but it would be such a bother to listen to it all over the house and that's before deciding if the programs are any good. You can't get cheaper radio than on the internet as the FM here and everywhere else is a load of godless crap music plugged by of delinquents who love to here their own voice.
Now I've noticed NOXON wireless internet radio with Ipod which I can use all over my house to listen to AM. Just waiting for it to hit the market - Bugger Sirius - only if they played 100% prog with live performances would they be a serious player.
