I look at it as WebRTC bringing the browser closer to an OS, in terms of the capabilities offered by the browser to application developers, out-of-the-box and without needing to convince or have users install something.

In terms of replacing, the obvious ones (as mentioned) are applications like Hangouts, Skype, GoToMeeting, etc.

In terms of enabling, time will tell but I try to think about what kinda of applications were possible before but not practical, because of the need to get everyone to install something. Hopefully this will increase the competitiveness of web to apps.
