What approach would you use to have other content displayed and searchable without frames?

I have various help pages for these widgets that have a lot of specific content about how to use them and other topics that someone using these widgets would be interested in reading. So, I’m displaying that content in an iFrame, while I keep the widgets loaded on my main page.

There is only one page that loads these iFrames, so even if you are correct about search engines penalizing sites with multiple references to the same iFramed content (and I can’t see why that would be, because, as another poster here mentioned, the referenced pages are being indexed on their own merits), I shouldn’t have a problem with that.

Now, as for navigation, I’m thinking how about putting in code that detects that the page is being loaded outside of an iFrame, and redirects the user to the enclosing frame, with an argument in the URL’s query string telling the site to load the original page in the iFrame? The only problem I can see with that is that maybe the search engines would consider that to be “cloaking?” Or maybe they would not index the page content because it was just loading a different page? Does anyone have an opinion on this? Anyway, one way around that would be to just have a link back to the enclosing page that the user could click manually, and only display that link if the page were at the top level (i.e., not in an iFrame).

It’s a complicated topic and I still haven’t figure it out.
