Me too. But I trust Nick and he's smart. I don't stick my finger into
every security pie because 1) I'm not an expert in all things and 2) I
have a finite life span and need to sleep.

So again my advice is: work with upstream/the community. You don't need
my input yet. Nick has spent far, far, far more time thinking about how
to fix Python/SSL/TLS then I ever will. Once you have a definitive
solution that you are pretty sure works, then please, by all means poke me.

This is a different project and related to web interfaces (which are a
growing pain point security wise).
