One of the things datacenter people want is to avoid dpdk-everything just because they put 4 200GbE in their server. I sure would like to just zmq everything... Especially for internal streaming applications, that would be a boon.

I haven't read the patchset yet but I'm wondering whether it would work with UDP. TCP can be too much 'kitchensink' if you don't need reordering or many-resends.
