Ack. Using named pipes requires some polling mechanism that works on 
named pipe HANDLE first though.

Yes. What's missing here is someone with IPv6 expertise to define exact 
semantics for IPv4/IPv6 interaction. The reason why original IPv6 
support was disabled was that it broke IPv4 :(

My understanding is that encryption support should be layered on top of 
0MQ. The rationale is that if the whole traffic is encrypted even 
intermediary nodes (devices) would have to be able to decrypt the 
messages to get the routing info (topics, identities, etc.) This in turn 
may be a problem in scenarios where intermediary node isn't trusted.
