P2P Contact Info Service From Napster Co-Founder

scrm writes "Plaxo is an interesting new service from Sean Parker, co-founder of Napster. It's a P2P-based add-on to Outlook that confronts the old problem of keeping contact lists up-to-date. Mozilla mail support is on the cards, and yes, the company does 'take privacy very seriously'. Check the press here(1), here(2) and here(3). You can also access your contact list over the web."
