In browser IM's not monitored

From what I've been able to find out on in these forums, messaging clients within a web browser are not monitored, such as Google talk in Google Plus or Gmail, Facebook Chat, Yahoo, or any other chat that's run in a browser window.  The responses I've seen going back a few years say this is a feature that's being worked on. How close are you to implementing this feature?

 

Also looking for full support of Chrome.

 

Thanks!
