Tokbox for videocalls

www.tokbox.com A new site for making video calls. Quality is not as good as Skype, but you don't have to install a programm (but you can) and video-conferences up to 6 people are possible. You also can sent a link to somebody, so it is possible to call you even if the other person is not registered. It's quite new, so expect it to be a bit buggy.
I wonder what other robots think of it.
