[BC] HD Radio -- Folks we have to get it right!

Thanks, Mike, for the information and presentation.  As I told Bob, I'm 
going to wait and see, myself... since it's not really a hunt that I've got 
dogs in right now.  I maintain my position(s) that IBUZ will fail in the 
marketplace, but unless I can get Vegas odds on it there's no reward in 
going short on this one ... so I'll leave it to others to toss their dice.  
:-)

Maybe the new former-bartender-head of the NAB can get the government to set 
aside $3 billion to buy everyone a new radio, huh?  Hey, there's precedent!  
It could come from the Homeland Security budget, given radio's long-time 
first-response to emergencies! "Cat's whishers don't work anymore, sir, 
we'll be needing billions to keep up with the state of the art so that the 
public can ignore our warnings..."
