It is obvious you have a considerable amount of knowledge in these issues, so 
I want to say Thank You for sharing your information with us. You've 
certainly raised some excellent ideas. The problem with what you propose, above
, is 
that Ibiquity is not sharing the technology... with *anyone*. They have it 
locked-up, and at last check (just a few months ago) the chipsets are $40 a pop
. 
Their "Licensing Infomation" pages on their WEBsite said "Add your content here
" 
for the longest time, and may still.

The other issue that it would appear you may have overlooked is the 
*same-channel* interference isses of the so-called "IBOC" (which is really IBAC
) 
system. For example, if a station on 1000 "lights-up" the HD system, they will 
be 
transmitting digital "garbage" on top of the stations on 990 and 1010. It isn't
 
"adcacent" to them, it is right on top of their analog signal. To get rid of 
*that* with DSP would leave a *lot* of artifacts, resulting in a still 
unlistenable signal.

I look forward to your response! :)

Willie...
