[zeromq-dev] Any concerns about having SUB bind to socket and many PUBS publish data to it?

[Charles Remes]

Pay attention to the SNDHWM on the PUB side and the RCVHWM on the SUB side. If you absolutely, positively cannot drop any messages then you should take a look at the "clone pattern" in the guide or consider using DEALER/ROUTER sockets along with an explicit ack/nak protocol (think zmodem or tcp). 

Outside of that, I can't think of anything else noteworthy.
