David,
I respect your approach, letting us know about your bandwidth study and what each network operator can expect. The important part is that we get the opportunity to either opt-out, or find out a way to "opt-in" and help you acquire more information to complete your research.
Too bad Digital Isle didn't follow the same approach.
Regards,
Christopher J. Wolff, CTO
Broadband Laboratories
