Just wanted to let you all know that I've just finished creating a Suite of Fonts for notation fingering for all the woodwind instruments:

http://www.tristandurie.com/Woodwind_Fingering_Fonts.html

Every font features an easy to use intuitive keyboard layout which mimics the instrument involved. The ability to notate full whole, half hole, trills and in some cases quarter whole fingering.
The Fonts can be used in music notation software such as Finale and Sibelius or text editors such as Microsoft Word and OpenOffice and most other programs that employ fonts.

I checked your link and really liked the idea. I have no application for it, but I am sure it could become a very useful addition for teachers writing their own lessons for their students. Congratulations!
