[zeromq-dev] Ingesting external data via TCP with 0MQ

[Brian Smith]

As mentioned in chapter two of the guide,
0MQ is not a neutral carrier [1]. You can't make arbitrary
connections with it.

Your only choice is build a gateway between the device
specific protocol, and 0MQ. Given that you already have
a listener written in perl, it shouldn't take you much time.
