Jim Hugunin's talks are always spectacular, and this was no exception.
He implemented generics for Python. Python doesn't really need these. However, it's necessary to interact with some .NET libraries.
He gave this great demo of the XNA game framework for .NET that targets both Windows and the XBox. Naturally, it runs the code in a sandbox. Because of this, Microsoft is allowing anyone to write code for the XBox. He wrote Python code for the framework. It was a really impressive 3D application with spectacular performance. Unfortunately, IronPython can't yet run on XBox or Windows mobile because that version of .NET doesn't support generating byte codes on the fly.
Apparently the guys from Microsoft Robotics Studio came to him to ensure they could program robots in Python. They wanted to embrace it from the very beginning. He gave a really great robot demo where a robot fetched a ball using software written in Python.
