One would expect the same transmission capability be used in an Internet car radio as for a cell phone when used in data mode today.
The question becomes how much bandwidth is taken up in the "return connection" when streaming. The challenge to me seems to be how does one adapt the user interface for an in-car experience; the same type of menu tree structure we see in Internet radios today is probably not too different from what one would expect to see in cars. And, as Mr. David mused, what is the capacity of a typical cellular network today for multiple simultaneous streaming connections? Sprint, Verizon, and AT&T all offer USB cellular modems today for the laptop-equipped crowd. I don't believe the impediments are all that great, given the technologies already in place for smartphones, wifi radios, and wireless laptop connectivity. I am not likely to be an early adopter, however, as I expect there would be a premium for "first mover" status in this space. When it comes to continuous RF exposure, I already use a wifi connection on my laptop, with no apparent consequences. Except for that eyelid twitch I've developed <g>.
