Hey Ron, if they are willing to give you airtime - this is NO BRAINER.
It will be non-prime time for a while, so what? In the age of the internet, this is no big deal.
You could get in depth with any subject at your own pace, bring in "special guests" for their input, interview with specialists, have charts, graphics, examples, footage from "the field", demonstrations, submitted questions from public, you name it, etc. etc. etc.
Seriously consider it Ron.
