Editor Controls within Game?

We are looking to build an artwork map (one of these things:

) and we want it to look as close to in-game as possible and the best way to do that is to actually have it in-game, we also want our customers to be able to explore it using the controls and movement they are used to.
My main question is has anyone got, or know where I can get a script to place on a camera to almost exactly mimic the movement and feel of the editor camera with the same controls, but for use on an in-game camera?

 

Anyone?

 

Sounds interesting, I'll probably whip up that script tomorrow night when I'm at the computer (hopefully I remember )

 

Great, we are in no huge rush for this, we have several weeks to do this.
