Plumbum is a Python library and tool to sort of emulate UNIX shell and pipes in Python. (I had blogged or tweeted earlier about a few different approaches to this.) Plumbum is creatively named - the word is Latin for lead, which was used to make pipes in earlier days.
You can read the Plumbum documentation here.
The creator of Plumbum is Tomer Filiba, who also created RPyC, a Python RPC library and tool, roughly similar to Pyro. Both RPyC and Pyro enable remote Python objects, allowing you to do something like what XML-RPC, CORBA and Java RMI do, i.e., communicate between functions or objects running on different machines in a network.
