[zeromq-dev] Zeromq xpub/xsub with Tornado

[Pieter Hintjens]

Hi,

I need to fix that section in the Guide. In fact there's a much more
detailed explanation on discovery here:
http://zguide.zeromq.org/page:all#Discovery

Which may help you more. Your nodes are all on the same network so you
can do UDP broadcast discovery (like the CZMQ zbeacon class does).
