I made trivial use of it in both testing and production to serve as a
collector for Apache logs. It was very little trouble, and did the
job, but was relatively painful to expand the network since it
required restarts of the service. The Apache log collector handled
that gracefully, but IIRC you need to specifically support it.
Performance was reasonable, but then...
I was using the 3.1 release at the time, though, so I have no idea if
4.0 or 4.1 improve on that.

...CPU load on the network was comparable to the load on ActiveMQ
systems under similar load. Spread isn't really much different
otherwise in terms of either speed, or being "lower level" (in either
the sense of being better for, or worse for, that. ;)
If I had to pick a "does as little as possible" low level library, 0mq
looks like the best available choice, but it provides next to
*nothing* in terms of scaling; you have a toolkit for messaging and
get to build out the rest of the routing, scaling, persistence, etc
