Just when I thought I might get bored on a three day weekend (here in the USA, it is Memorial Day weekend) Varun Srinivasan, a program manager on the OneNote team, put together a How To to get Python working with OneNote. Details are at his blog: http://varunsrin.posterous.com/python-onenote-you
The teaser I will leave you with is that this is essentially only three lines of code.
Nice work, Varun!
Now to dig into this myself...
