You could get bukkit installed and running in just 15 minutes together with RaspberryJuice. Juice is a craftbukkit plugin and is the glue between the bukkit server and Python - it sets up a UDP port listener which mcpipy talks to via an API wrapper providing a few python classes for your use.
How to get started with mcpipy http://mcpipy.wordpress.com/author/mcpipy/page/2/ - note mcpipy is not a install-able module at this point, you can down load it by following the next few steps which include a bunch of example Python programs.

To get a good batch of sample python scripts, install Git. Here’s one git-guide covering Windows, Linux and Mac. http://git-scm.com/book/en/Getting-Started-Installing-Git
Open a command prompt.
Create a directory where you want all the scripts to be stored — such as a “mcpipy” directory
Change into that directory
Type “git clone https://github.com/brooksc/mcpipy.git”
