[zeromq-dev] zeromq and crypto?

Is there a recommended way to secure the underlying zeromq
communication with crypto?

Given a N:M publishers and subscribers,

1. Should apps establish connections point to point between each N and
M using something like stunnel, which zeromq can then use the tcp
transport over?
2. Is vpn a better idea? (I guess this only really works if a customer
is able to do this).
3. Should apps, instead, use crypto libraries to secure the zeromq message body?
4. Is there a zeromq transport in the works, ie tcps, for secure connections?

Has anyone tried any of the above? I'd love to hear your experiences,
and any issues with stability and/or performance.
