P2P Meets PSTN, With Bellster

flinderhans writes "Jeff Pulver, the guy who started Free World Dialup (free VoIP network) and had the germ of the idea that turned into Vonage, has launched a P2P network called Bellster that allows users to share their private lines to make calls anywhere on the public-switched telephone network. Interesting stuff, even if it doesn't look quite ready for prime-time."
