Plain Ajax or Iframe and Ajax for CMS administration interface

I think iframes are a pain with regards to using the back button. Google Mail seem to have it sussed, though. The back button works beautifully in GMail, and they use IFrames. I'm sure this can be fixed if you do a redirect on the IFrame when it's done it's business. That should prevent any data being submitted more than once, and might help keep the IFrame in sync with the main window.
