I guess I'd better get started on making it then :) The scenes are rendered to FBOs so they're not tied to any particular window/context or display method. The scenario is that a user will set one scene to be rendered and sent to an external display system at 60fps. Once the first scene is rendering the user can request a preview of a second scene. When the preview is ready the user can seamlessly switch the system to rendering and sending the second scene at 60fps. As far as I can see to implement a solution I'll have to duplicate a lot of code from RenderStage/RenderBin, unless you can see a more elegant solution? Thanks for your help
