[zeromq-dev] design for peer to peer messaging

[Pieter Hintjens]

Michael,

In general it's not useful to design a 0MQ architecture until you've
fully internalized how the different patterns work.

My advice is to make a *minimal* working design with one of each
piece, add more one piece at a time, and work out the issues like
that. When you've done this a few times it'll be obvious.
