You could implement Spread using 0MQ (quite nicely, probably) but not
vice-versa. Spread is a pattern for reliable group messaging, i.e.
guaranteed delivery of a message to multiple nodes. It is very slow
compared to raw 0MQ messaging (thousands per second afair) but does
way more work.

BTW doing proper reliable group messaging seems really hard. Perhaps
someone with experience in this field will one day make a 0MQ pattern
for it. I had a quick shot at that, and did not succeed.
