Firing quite the shot across the bow of its satellite radio rival, Sirius Satellite Radio CEO Mel Karmazin told audience members at a conference on media convergence that he'd happily buy XM Satellite Radio. Executives from XMSR (surely wondering what "the right price" might, exactly, mean) hadn't commented, yet, at the time of this post.

That would be quite some convergence. As the two companies have raced each other to forge deals with opposing car makers and big media names, and have struggled to out-innovate and out-subscribe one another, it seems as if nothing defines the sector so much as the rivalry.

Monopolistic concerns would certainly be raised by regulators, although really: what harm could come of having only one satellite radio company? It's not like consumers have no other choice for their listening pleasure in their cars, or anywhere else, for that matter -- what with offerings ranging from the iPod to the common FM station.

Regulators, it's possible, wouldn't agree with my "who cares?" analysis: they stopped an earlier proposed deal between DirecTV and Echostar.
