The Web Content Accessibility Guidelines require that Frames have meaningful names/titles, and should also have alternative navigation mechanisms provided by use of the NOFRAMES element - in many cases access to individual frames causes a significant loss of context and proper use of NOFRAMES is much better. (In addition, it provides the ability to make a "deep link" - bookmark a relevant part of a framed site.)

From an accessibility point of view, if you are going to have frames, at least label them clearly and sensibly. This should go in the WAI content guidelines. BTW, couldn't the assistive technology (user agent) treat frames as separate pages? I would assert that frames are essentially pages that can be simultaneously displayed on the screen. If they were treated like pages, there'd be no problem with the back button!
