Need an Elegant Solution

This discussion may prompt another brain dump...if so, this noob would like to apologize in advance and thank any dumpers who care to enlighten me.

I have quite a few users who generate school-related newsletters (mostly in print) and I'm finding that many use MS Publisher to do so. They would like to be able to post their creations into the district web site and have the content appear with included graphics, active links, etc. I guess the basic question I'm asking here... Is there a right way to elegantly accomodate something like MS Publisher content in Drupal 6?

The approach I've taken thus far (just as proof-of-concept) can be seen at http://stc09.tamatoledo.net/?q=node/460 and works something like this:

1) The user creates his/her web content in MS Publisher and opts to Save As "Web Page, Filtered", then elects "Publish to Web" using an FTP profile that deposits the index page as a .htm file along with the bulk of the content which is stored in a folder named to correspond with the HTM file. In the example posted above the web page is stc_test.htm and the folder is stc_test_files.

2) I created a content page and the body of the node is simply an iframe tag coded with src="./ftp_path/stc_test.htm".

3) That's it. Short and sweet but not very elegant.

The end result appears to be exactly what I wanted but the drawback is obvious... the page has to be coded with the name of the uploaded .htm file. Is there already a better solution in Drupal or am I looking at creating a content type and module to do this properly?

If a custom module is the solution then I'm imagining something that would prompt the user for their .htm file and folder, upload them both and subsequently build a node to display the page(s) inline. Am I way off the mark here?
