Anybody has suggestions for WebRTC API platfroms?

In more details:

I'm developing a web application with a few real time communication features:

1. Video chat.

2. Interactive map: This feature is based on the GoogleMaps API. Where two clients share the same google-map and can edit it in the same time. Additional they both can do different actions such as zoom in/out, moving from one location to the other etc.. The goal is that the map should be synchoranized between them. So if one of them is zoom in the mapped is been zoomed-in on the second client screen.

For the first feature I think there is no problem and allmost any platform can handel it. The second feature is more complicated and is dealing with real time data sharing.

Anybody has suggestions?
