Pyro

One of the best thing of scripting languages like Python is the ability to fast prototype complex things. In the past ten years, if you like to build distributed application you was forced to use huge and heavily languages like Java.

On Python there is a nice library called Pyro, which used with success:

Pyro is short for PYthon Remote Objects. It is an advanced and powerful Distributed Object Technology system written entirely in Python, that is designed to be very easy to use. Never worry about writing network communication code again, when using Pyro you just write your Python objects like you would normally. With only a few lines of extra code, Pyro takes care of the network communication between your objects once you split them over different machines on the network. All the gory socket programming details are taken care of, you just call a method on a remote object as if it were a local object!

Pyro provides an object-oriented form of RPC. You can use Pyro within a single system but also use it for IPC. For those that are familiar with Java, Pyro resembles Java's Remote Method Invocation (RMI). It is less similar to CORBA - which is a system- and language independent Distributed Object Technology and has much more to offer than Pyro or RMI. But Pyro is small, simple and free!
