[zeromq-dev] czmq / zauth

[Joe McIlvain]

Greg Young,

As a shameless, somewhat off-topic plug, I've been working to write a
ZeroMQ implementation in Pony, which happens to be an actor language where
each actor is not a system thread, but a more "green" representation as you
describe.

I've found that the CZMQ actor paradigm have been very much in line with
Pony's paradigm, and that working with CZMQ did a lot to get me in the
right mind set for writing Pony applications.

It turns out that you don't need to use inproc ZeroMQ sockets to pass
messages between actors within your application, as Pony has its own
mechanisms for doing that, so the main focus of my ZeroMQ port has been to
support interoperability with external applications in other languages (but
I also included inproc sockets for consistency).

My pony-zmq package: https://github.com/jemc/pony-zmq

Thanks,
