Server to show multiple camera views of clients?

Hi. So i am trying to make a 4 split screen on the server side with 4 cameras with different viewport rects. Each camera will show what each client sees, including their user interface. The clients camera is always static.

Currently what i am doing is, the clients menu object which is instantiated on the network, has a networkview with a script being observed.
I was wondering is there an easier way to "see" the client's camera view on the server? or do i have to networkview everything that i want to sync up with the server?

 

An easier way huh?
Either put networkviews on those objects, or sync them using RPC's ;o
