Shared Websocket connections over multiple tabs

I'm trying to find a solution to avoid multiple connections over multiple open tabs. Instead, I'ld like to share the connection between them (especially since users tend to have up to 30 tabs open sometimes). Now, I'm apparently not the only one with the Issue, and after searching around for informations for a while, I found this 2 year old entry: https://groups.google.com/forum/#!topic/socket_io/FbHU7HvxK6U

I have a solution outlined which will probably land in 0.9.

Now, I'm wondering: is it implemented? Does it work? I couldnt find any informations about it, and I'ld really like to solve the problem over socket.io instead of creating a strange localStorage hack to share a connection.

Thanks in advance, I hope there are some good news - would save me a lot of work ;)

The issue names no source files, tests, or entry points. Start by determining whether the current Socket.IO client supports sharing a connection across browser tabs and clarify browser support, lifecycle, and fallback requirements; done should be defined as an agreed, testable behavior for avoiding unnecessary per-tab connections.
