Using an external binary to transport SSL or TLS is a hack IMO.

It's a headache I'm willing to endure for the sake of Emacs users.

The alternative, which João is enduring now, is to punt the problem.

This is a question for the Emacs maintainers: do you agree with me on
the above plan?  It would mean changing the way Mac OS X and W32 Emacs
builds are distributed, to include the GnuTLS libraries with the build,
and we'd have to implement a way (perhaps through the ELPA) to
distribute updates to these libraries.

Did you propose a patch?  I would commit a patch but can't write it
despite your great description of the problem.
