Yes, it is an interesting idea.
The author of filenotes here http://geoland.org/2007/01/filenotes-windows-tagger/, (not the Moonsoftware app) says that
If you click on the notes file it should open up the associated file.
Cool. I wonder it the trick still works if files are renamed, moved, etc.

It really isn't much of a trick. A file named Amando.jpg would open with your graphics viewer.
When you use one of the filenoters the app adds an additional extension to that file NAME!! and opens a text editor associated with that extension.
The app you mentioned above would add notes so your new text file becomes Amando.jpg.notes and by default opens in Notepad. When saved and your files are displayed by name the two files are adjacent to each other in the folder.
Change the extension to Amando.jpg.txt and the files will still be adjacent in the folder but the file, in my case, will open in Metapad, which is my associated editor for txt files.
If you rename the file to Cuffy.jpg.txt it will still open with the associated text editor but the file is now displayed in the folder with the "C"s rather than with the "A"s and the purpose of writing the note has been defeated.
You'll suffer an even bigger defeat if you move the note file to a different folder (or drive?) unless you are using a different system for files.
One could easily move all notes files to one folder to be used as an index, etc. but in my case I want to include a note that Avast.exe was downloaded 12 Dec 07 and the serial number is xzzzxxxxxzzz#!. The folder displays
Avast.exe and immediately below Avast.exe.notes
Renaming either won't change the file contents nor it's Open with......... app but it will split the location from adjacent to afar??
Hopefully that answers your question? I'm quessing that you have an idea to use filenoter in a different manner than I do. Give it a shot!
