I wanted to link again to Olya's blog where she outlines sets to get a OneNote IFilter installed on SharePoint:
Enabling searching of OneNote content on SharePoint sites
SharePoint sites are great for storing OneNote shared notebooks for team collaboration. The OneNote New Notebook Wizard promotes SharePoint sites for storing shared notebooks. If many teams in your organization store their notebooks on SharePoint sites, you can enable searching OneNote content via SharePoint search.
It is necessary to install OneNote on the server and to register the OneNote IFilter in order for the OneNote content on SharePoint sites to be searchable. To do this, follow the steps below:
Windows SharePoint Services
Note: the steps are different for SharePoint Portal Server and Office SharePoint Server. Please, see further below.
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Shared Tools\Web Server Extensions\12.0\Search\Applications\961ddf2b-49a8-4a2f-ac9f-a5a14a0096f8\Gather\Search\Extensions\ExtensionList]
If there are 37, you will need to add OneNote as the 38th value. If there are 38, OneNote will be 39th, and so on.
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Shared Tools\Web Server Extensions\12.0\Search\Setup\ContentIndexCommon\Filters\Extension\.one]
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Shared Tools\Web Server Extensions\12.0\Search\Setup\Filters\.one]
SharePoint Portal Server or Officer SharePoint Server:
If your document libraries require check-out to edit the files, OneNote files will often be in checked-out state. The new additions to the files will not be searched until the file is checked in. In general, we recommend to turn off the "require check-out" rule for document libraries intended for storing OneNote files.

Awhile ago I got a few emails from you all about how to get search in SPS & WSS to support OneNote
Can it crawl handwriting in OneNote?
Thanks a lot. Jacky
Is there a more revealing way to get the metadata out of the .one file stored in a sharepoint site to be used and referenced by a custom built minute not taking in house app we designed...really curious how to do this.
Is this relevant and /or applicable to SharePoint 2010?
