Usage

using ZMQ

s1=Socket(REP)
s2=Socket(REQ)

bind(s1, "tcp://*:5555")
connect(s2, "tcp://localhost:5555")

send(s2, "test request")
msg = recv(s1, String)
send(s1, "test response")
close(s1)
close(s2)

The send(socket, x) and recv(socket, SomeType) functions make an extra copy of the data when converting between ZMQ and Julia. Alternatively, for large data sets (e.g. very large arrays or long strings), it can be preferable to share data, with send(socket, Message(x)) and msg = recv(Message), where the msg::Message object acts like an array of bytes; this involves some overhead so it may not be optimal for short messages.
