[zeromq-dev] Can I change a socket mechanism after a connect ?

The security mechanism, like some other socket options, applies to the
next connection (in or outgoing). A single TCP connection cannot
switch between mechanisms. There's no protocol for that, nor is there
any sense in it. Changing security level on a socket after having
connections is also dangerous and we've discussed banning it.
