Awesome XSI - ICE Dynamics

EDIT: After digesting the contents of the videos over a few days I want to change this post.  Initially I was, and still am, impressed and blow away by the awesomeness of these dynamics. Definitely some things in here that would be extremely hard to do get maya to do, but at the same time, I've also only once in my career had an need for most of those hard-to-make-in-maya fx.
Unlike Fume FX which is still the leader in my mind for smoke, fire, and explosion fluid solves, thats something I need often.  
I'm excited to see where Lagoa goes, and still very impressed and inspired by the demo. I would love to find out the sim times on it, which could be impressive or sim-ilar to RealFlow which is the standard.
