The event loop conflicts you mention can be avoided if you use a wrapper
library to integrate zmq sockets into the Twisted event loop. There are two
options for doing so that I can think of off-hand:

One of the widely accepted failures of the existing TLS security model is

Great start Diego. I've been wanting to work on SRP for ZMQ for months now

This looks great Pieter. The lack of a good security mechanism has been a
stumbling block for me in the past and I'm glad you have a good plan in
place to address it. I'll admit though that I was a bit disappointed a

At a meetup just short of a year ago I was asked to post to the list
about a Paxos over ZeroMQ side project I'd been working on. At the
time, the implementation was roughly alpha quality and the code wasn't
particularly clean but it seemed to be fairly well received. For those
that are still intere
I have a use case coming up that requires secure communication between
two remote nodes that have an arbitrary number of message relayers
sitting in between them. In this particular case, some of those
machines will be using unrouteable IPs so most of the traditional SSL
tunneling solutions used in
One thing to note with the Paxos option, if you decide to go that
route, is that the number of participants in the decision making
process doesn't scale all that well. Typically, a sub-set of nodes (<
30 or so) is used as the decision makers and everyone else just
listens for the results. Also, tru
The hmac module in the Python standard library may be easily used for
message authentication and integrity needs. As for encryption, the
pycrypto module will probably meet your needs. Assuming that both the
publisher and all subscribing nodes share a secret key, it's

While attempting to unit test some code based on PUB/SUB sockets
(pyzmq 2.1.10 & zmq 2.1.11), I ran into an unfortunate race condition
that occasionally breaks the unit tests. Usually the message exchanges
work fine but occasionally the unit tests randomly break due to some

At today's ZeroMQ meetup in Chicago, a surprising amount of interest
was expressed in a Paxos/ZeroMQ side project I've been working on for
the past few months. At the request of several of the attendees, I've
made the code publicly available on GitHub for the perusal of anyone
that's interested.
