Cool! Its amazing what we can do with WebRTC. I create this site (https://github.com/imomin/videoChat) just for fun.
Are you guys trying to replace Skype? Because, that is what most freelancers and contractors are using it.
We definitely see people swapping for Skype, yes. We're not trying to replace it for general communication - as an internet phone Skype is excellent - but for collaboration, not so much :-)
