glxinfo over X-forward will report on the display the client is drawing 
on - X clients are not aware of any other displays unless explicitly 
instructed (e.g. glxinfo -display localhost:0), and even then you'll 
have to fight xauth.

Incidentally, you can never do direct rendering over remote X connection 
because the client (which is executed on a remote system) does not have 
direct access to the memory of the display.
