Anyone else using or interested in Zeromq?

I've been using this library on the job for a while.  My use case
is distributing phone system events around our network, we have
not worried about guarantees of delivery.  I am planning on using
Zeromq to publish moteino originated messages collected on a Raspberry Pi.

Has anyone used this or any similar network framework?
