Remote Procedure Call support, for exposing local function as public services, and calling public services on remote applications.
Wraps around ZeroMQ for messaging. http://www.zeromq.org/
This is a very basic module that allows you to create an application which exports various functions as services, and then to have client apps call these services almost like a native python call.
This module uses ZeroMQ for the messaging functionality: http://www.zeromq.org/ It should get installed by the setup.py installation process. But on some systems you may need to install this seperately.
The GUI-based examples require PyQt4: http://www.riverbankcomputing.co.uk/software/pyqt/download http://qt.nokia.com/downloads

>>> python setup.py install
or
