Voice-Over-IP Lands On Mac Desktops: Skype For Mac OSX Is Here! - RG News

Well it's not the video chatting you were looking for but let me say
that Skype (for Windows and Mac) has amazing, amazing quality for a
voice chat. I've chatted with a couple of friends in Japan and it's
like they're really there (my brother who was on the phone with me one
time said "Is ... is Takeshi visiting?").

And it's free.
