iRadio sounds like it will essentially be a podcasting radio station.
And AOL will most likely put their own AOL Radio stations before Shoutcast stations.
But for the record, Motorola isn't the first to move web radio from outside of a PC. Linksys, Intel, iPod, and a few others have already done this by creating products like boomboxes and also devices that broadcast an Internet radio stream straight to your car radio.
Right now, it's just a matter of supply and demand. Verizon's VCAST is testing that out with their broadband streams shooting through a cellphone.
