I share your concern re: the lack of response from EDIG re: possible business. I`ve had some success in coordinating with the company in the past, and actually got cooperation (albeit it was years ago and not about new business, but info for an article - but they do remember me from that past positive experience in recent contact).
If you (hopefully) would like to pursue this further, I wouldn`t mind coordinating with you to get a ``familiar to EDIG`` name on the face of your queries (so they know it`s not competition or some nefarious email).
You can contact me at rbslack1@yahoo.com
I look forward to hearing from you. Your idea appears to me to have merit worthy of EDIG consideration.
