Rural Telcos Blocking Vonage?

I ran into Mike “TechDirt” Masnick over at DEMO yesterday – we chatted about among many things Vonage, and who was blocking it. I think a lot of people misunderstood my last post about Vonage blocking, assuming it was SBC who was doing the blocking. Mike pointed out correctly that some rural phone companies who are doing the blocking and tackling of Vonage. Thought I would post a quick update.
