Regarding this specifically:

It's not possible to establish a secure channel without a prior secure
channel. For infrastructural use of 0MQ I think it would make sense to set
up a certificate authority for a grid, and issue node-specific certificates
which are then signed by the CA.

Have you thought about how to deal with things like CRLs?
