Align to the 3D Viewport?

Is there a way to align a bone to the 3D viewport.
I want to get a set of bones (in fact an IK-FK group of sliders) always facing the viewport.
Is that even possible?

Um, do you mean to camera view? Because I think if that is the case, then you could parent the bones to the camera in some way. If not, then I dont think so since the 3d view is dependent on which view you have chosen from all the options.

Thanks for the answer.
I meant the 3d view, not the camera.
Too bad. I though the 3D view surely has a matrix anywhere and maybe it could be possible to get that matrix for doing the trick.
