the multiprocessing module has "Managers" which can be used for IPC. I'm guessing that you could just communicate with those via Unix sockets, or TCP sockets on 127.0.0.1 and get pretty comparable results with 0mq, no? I've been using managers over TCP for use as an image cache (the program is essentially an image resizing proxy), and in my limited benchmarks, it's fast enough. Now, this isn't some real-time trading application, so maybe 0mq would squeeze something, but TCP/Unix sockets is probably fast enough for most purposes here.
