That depends on your workload. 0MQ is fine software, but they solve different problems.
The problem here is the claims you're making. You've written some utility classes around 0MQ for some applications, which is a real thing, so I'd rewrite your GitHub readme to just demonstrate what problems you've solved with it (and at what kind of scale). Making big, sweeping claims gets you into these kinds of threads, because extraordinary claims require extraordinary evidence :-)
I use it everyday for some of my home baked apps, and would love if this really made a difference.
