This is incredibly awesome, I have a huge amount of respect for Crispin, he's one of the most respected researchers out there.
Among other things, Crispin's the author and designer of AppArmor, which adds sandboxing capabilities to Linux. Apparently he's going to be working on the core Windows Security team, which is absolutely cool.
I'm totally stoked to hear this - I literally let out a whoot when I read Michael's blog post.
Welcome aboard Crispin :).
