GNU Free Call has been announced (Skype-like software)
The sad fact of the matter is most people do not give a hoot about software being open.<p>I honestly do not think you stand a chance competing against Skype, it is <i>so</i> insanely great and wide spread. I'd be impressed if they can actually make the UI/UX <i>better</i> than the latest (horrendous) Skype client.<p>It's like the Diaspora of VoIP.
