Thanks Benjamin.
They are using them to facilitate the menu/header/footer ite,s across a
host of applications which sit on a range of differing servers using a rang
of differing technologies. I suggested SSI's but that is not possible due
to server configuration issues. I think I am going to allow iFrames but
with some stipulations.

WCAG 2.0 tries to express the principles of web accessibility in a
technology independent manner. If you can use frames in consistency with
those principles, that's compatible with conforming to WCAG 2.0.
Note that the Techniques document for WCAG 2.0 does include some HTML
techniques relevant to frames:

The usability minefield with frames described at -
http://www.useit.com/alertbox/9612.html
- hasn't disappeared.
The interoperability problem hasn't disappeared either. There are still
browsers in use - some mobile browsers, Lynx - that can't handle frames.
More recently, security-conscious users are being advised to disable
"iframe" support as one measure against clickjacking:

Likewise the problems with frames for search engines described at the
article Nielsen cites:
http://www.ehsco.com/opinion/19980209.html
appear to still exist today:

Use them how for what?
