I fail to see any comparison here. WebRTC is a project building support for things like P2P and Device API support into modern browsers. This is so you could do things such as access a user's video camera through the Device API and establish a P2P stream with another browser, without using any Flash or installable plugins. Now is just a JavaScript library that enables you to do RPC with browsers.
