Facebook officially havenâ€
Initially only Facebook users can participate in chat, those who choose to install the browser plugin, but later Vivox plans to dial-in numbers that will allow even non Facebook users to participate in the conversation.
Vivox is currently in private beta and will launch to public in Q4 2009.

I don’t use FB chat all that much (for voice or video chat I usually just Skype) so I wonder how this would compare in quality. Sounds potentially really cool though.
