This shit is going to get better and better. Gotta keep it Free. (clicky clicky on those devils if you haven't)
It's the beauty of the marketplace, man. You speak with the voice of a billionare investor. That's a loud voice. Sometimes you get spoken back to by a few thousand of us little people. Welcome to parity.
The problem with teiring service is not that the principle of Network Neutrality is involuble. The poster above who suggested home-alarm data as that which could be "privileged" is correct. There are already laws around this that impact things like 9-1-1 service.
But if you really think BellSouth wants to tier internet service so grandma can get a video checkup, I've got a bridge here in Brooklyn you've just got to see. We don't have technology or trained personnel to even begin to imagine that as a reality. It's pure vaporware spin.
On the other hand, you're a founder of HDnet, a company that produces video entertainment of the highest-bandwidth that conumers can currently recieve. It's pretty easy to imagine real ways in which tiered service might be of use there.
Here's what I believe: If large corporations determine how internet traffic will be teired, it will almost certainly not be done in the public interest, or in the interest of creating a vital market for service and data online. It will almost certainly be a move to consolidate the existing marketplace, to commoditize and productize the network, to turn the internet into a consumer medium.
This will raise higher barriers to entry. It will stifle innovation. It also threatens the principles of standardization and interoperability: a "market driven" tiering structure would likely lean towards propritary technologies and business practices, creating corporate/national vertical silos which may impair global connectivity.
The great pracitcal benefit of the internet has been the decentralization/re-distribution of the means of communication. That's what makes all this cool, really. Incidentally, is also the phenomena which enabled your fantastic personal wealth. (Yahoo made you a billionare. Their money comes from harnassing online communication.)
Color me cynical, but I'm unconvinced that your support for net teiring is motivated by a desire to "keep the net healthy." I suspect it's about maximizing shareholder value.
