Sure, but this has to start with the app_server, not Screen. If you 
hack something together now, it will likely be thrown away later, 
anyway.
The current hacky multi-screen support of the graphics cards add little 
value IMO.

Please read this blog post to see how multi-screen support will work 
under Haiku:

He worked on it from the POV of a graphics driver - when you have more 
than one card, you'll likely have to coldstart the card in order to get 
it to work.
This is completely different from what the app_server has to do. Also, 
the current accelerator API does not really take mult-screen into 
account (ie. multiple screens coming from one card).

You either have to run Haiku on a real machine or an emulator of your 
choice - or run the test environment on R5.

Since it's not yet clear how the app_server support for multiple 
screens will look like, it makes no sense to start with a preferences 
application for it now.
