ZeroMQ: Can we .bind() 100+ sockets to the same endpoint?

Is it a good idea to have multiple PUSH sockets .bind() to the same endpoint?
1) If yes, how can multiple PULL sockets .connect() to this endpoint and start receiving messages?

No, the first .bind() typically grabs the resource ( ref. the port )

The next thing is, that PUSH Scalable Formal Communication Pattern has a hardwired "internal behaviour" - the API table says:

Outgoing routing strategy Round-robin

so, if there were more than one active transport-class connections to the PUSH-node archetype, it will cyclically distribute the outgoing messages to the connected, active PULL-node peers ( in a uniform load-ballancing, literally in the "round-robin" manner ).

However, it is possible to groom the intended outgoing traffic from several PUSH-ers ( by a local mediator / job-collector ) and expose such uniformly collected flow of jobs ( messages ) under a single "public" PUSH-ing node to all the external PULL-er(s) ( all the currently active peers get served on the round-robin basis + decide on using the .setsockopt( ZMQ_IMMEDIATE ) )
