That's not to say it won't be possible, i suspect that with sufficiently tuned rendering settings the GPU additions to Lux will enable remarkably quick renders. However, getting that ramped up to multiple or tens of frames per second is a different matter.
While waiting for computers to get fast enough for real time unbiased viewports, I'm now dreaming about an intermediate status. Instead of rendering in the 3d view directly, I'd like to have the option to dedicate one Blender window to LuxRender output while having another window open as the normal 3d window. Then whenever the user sees fit the Blender LuxRender viewport should start to render an image from the same camera angle as the main 3d window.
While this may not seem that different from the current situation with LuxRender and Blender running next to each other, not having to switch applications would make the process feel smoother. If the program could use the 3d window view instead of the active camera that would be a bonus as it would save another step in the process. Also it would be great if textures could stay in memory to save another few seconds of loading time.
