Maya 2011 Dockable UI Windows

Does anyone know how to gain control of 2011’s dockable windows such as the Attribute Editor, Layer Editor and Channel Box so I can change their positions on screen through script?

I’ve been able to access their formLayout in order to change width and height (to a limited degree), but have not been able to figure how to modify their current positions.

Unlike a lot of the other panels, such as the Outliner, they don’t have a top level window I can modify. Instead they seem to all reside within the main ‘MayaWindow’. And unfortunately the MayaWindow doesn’t seem to give me access to those individual editors I listed.
