Clay Shirky [via Joel]: ZapMail and the Telecommunications
Red Herring: Baby Bells cry foul
I was having a conversation about this stuff with Michael Winser (when are you going to start one of these blog thingys?). He is a happy user of Vonage and is working on trying out some of the other services. His comment was that these VoIP solutions will be too successful and the phone companies will try to regulate them out of business.
