I just published/open sourced a Web Exporter utility I wrote for OneNote 2007 that lets exports a notebook as as an interactive web site like this:

OneNote Web Exporter 

Useful when you need to make a notebook available to people who don't have OneNote 2007 (and don't want to/can't install it). You can also schedule exports regularly to keep the webview up to date. With some creative use of SharePoint webparts, you can even make your notebook viable through a SharePoint site.

Go here to check it out: http://www.codeplex.com/ONwebber

I'm going to keep working on it in my spare time, so feedback/comments/suggestions would be super useful.

 

(Thanks for blogging about this Dan!)
