From reading the description, and from what little I know about IronPython...
IronPython is a re-implementation of Python in C# which allows it to play nice with .NET. This is similar to Jython which is a re-implementation of Python in Java that plays nice with the JVM.
This project on the other had is not a re-implementation at all, but aims to augment the existing CPython implementation with JIT APIs and is using CoreCLR for the JIT.
What ericfrederich said is all accurate. We are also considering playing with ChakraCore as a JIT back-end as well once we are sure that our abstract interpreter code that drives the JIT emission code is compatible with Python semantics.
