I assume you mean symmetrically bidirectional?

If so, a pair of PUSH/PULL (or PUB/SUB) on each end would provide that.

I don't know what this means here.

Also, unclear to me. 

Client-server implies reply-request which is not (symmetrically)
bidirectional.

One DEALER may send the same request to many REP or ROUTER sockets.
