Having read Artificial Intelligence: A Modern Approach (http://aima.cs.berkeley.edu/), I think it would be a neat side project to abstract as much out of the intelligent agent model from Chapter 2 as "makes sense" and see to what extent you can allow interfaces from any programming language.
Seems weird to see a coding competition with only one language available.
Maybe you'll be able to improve that in the future?
EDIT: It would be great to have python available. But an API that any language could use would be the best way to go as the other comment mentions.
I just wish there were more AI contests out there, they are some of the most fun I have programming.
