RBehave with NUnit

I just read Dan North's article on Introducing RBehave. In a jealous rage of not being able to utilize Ruby fully in .Net. (YET) I decided to see if I could pull off what Dan had created in rbehave using NUnit. Because I am a huge proponent of reuse, I didn't want to extend my existing Test Coverage with a brand new framework. After all BDD coupled with ReSharper and Visual Studio make for happy testing.
