Cool :) We thought the same too.

Not quite.  But there is a sample about IFRAME-s that you might be interested in.  See examples/iframe.html from the trial package.

We strongly believe that frames (as in a frameset) are bad for many reasons including accessibility, search engine optimization, etc.

Well, just add style="display: none" to the UL that defines the menu, include a DIV containing the text "loading please wait" just before it and set that DIV's display style to “none” from JavaScript right after calling DynarchMenu.setup in your page onload handler.  Hope this answers the quesiont. 8-)
