pyzmq master has zmq.ROUTER/DEALER.  Note that you can just add constants
that pyzmq is missing, by simply adding:

zmq.ROUTER = 11
zmq.DEALER = 12
# these values are specific to zeromq >= 3.0, since ROUTER/DEALER==XREP/XREQ
in 2.1.

at the beginning of your program. As far as pyzmq is concerned, all of the
socket types, etc. are just numbers.

pyzmq is all ready to cut a release (I even built an entire 2.1.8 release
two weeks ago, before 2.1.8 was demoted to a release candidate), so as soon
as zeromq cuts 2.1.9 pyzmq will follow suit.
