Chuck, you raised a very good point for the use of "Multicasting". The option 
has always existed, tho... SCA channels have been around for, what, 40 years? 
Reading/Info services for the Blind have used them successfully for a long 
time. Sure, the audio isn't fantastic, (it's not bad, either) but with today's 
tech, a "simple" DSP chip in an analog receiver would make a dramatic 
improvement with a minimal increase in cost to consumers. Make the whole subcarrier 
digital (like that DRM/DRE proposal) and then you'll have far superior quality 
sub-program channels without all of the drawbacks of IBUZ. (Which we know are 
many.)

The consumers ask, "What's in it for me?" so the lower the cost to them, the 
better. 

Willie...
