I would only note that the scenario I just heard described really does rely heavily on Vonage and some of these other third-party providers coming forward.
That's one of the reasons why net neutrality advocates are so concerned, because if you're creating a system whereby you're really looking to these third-party providers as a critical component in terms of the overall competitive marketplace, there is an incentive built in for the cable company, as we've already seen in other ISPs, to try to block access to those services because they've got the customer built in, and the technology makes it easy to ensure that you can keep Vonage out if you really wanted to.
