WebRTC is an API that used the new P2P web API to allow developers to implement audio and video communications using direct P2P links between browsers. This really is a game changer." And, while this feature doesn't seem to have gotten a lot of attention so far, Google Voice can call landline and cell phones for a small fee, just like Skype.
