Is there a way move the current perspective viewport through a script? Is the perspective view actually a hidden target camera that can be accessed like the root scene node or a group's parent gizmo?
Nope, a perspective viewport is not a camera, but it has a transform matrix and FOV value, so you can manipulate these as of it were a camera. See viewport.GetTM() and viewport.setTM() methods for getting and setting the matrix. The TM is equivalent to 'inverse $Camera01.transform', so you can set a viewport to match an existing camera by setting the TM to the inverse of the .transform of the camera, then set the FOV, too.
aCamera = $Camera01
viewport.setTM (inverse aCamera.transform)
You can of course transform the view as you want using matrix operations. The viewer's position could be acquired by using (inverse (viewport.getTM())).row4 and so on...
