I've already done some work on it. For now, it's on the back burner
somewhere. Simply finding all the relevant standards[1] was a
challenge. I want easy, cross-browser form signing, so it does need to
be completely in JS.

As someone mentioned elsewhere, you could easily write a GPG-based[2]
extension. This is the approach taken by Enigmail[3] (PGP for
Thunderbird and Seamonkey). Enigmail is pretty complicated, but I
think you could get away with something simpler.
