[zeromq-dev] zerocopy and PF_RING

Hi all,
just out of curiosity (since I see PF_RING being mentioned), was DPDK ever
took into account?
My company is now using DPDK for very-fast networking capture (let's say in
10-40Gbps range) and (very recently) adopted ZMQ for inter-software
communication (much lower bandwidth)... while zeromq is much more friendly
than DPDK having a ZMQ PUB socket over DPDK would just be awesome :-)
