It’s probably not quite what you had in mind, but take a look at this old post of mine: http://www.outlinersoftware.com/messages/viewm/4871

I see that the program mentioned, Nemo, is under continued development and has almost reached v.1 http://www.nemo-docs.com/ (a long way ahead of the Linux version)

Other than that, I know that there is at least one file manager discussed here in the past which allows you to enter notes for any file and view them when browsing, but I am uncertain of its name—Filenotes ot something similar I think.
