Pretty awesome, I for one don't think the constant stream of "x, rewritten completely in javascript" is tiring (this is not meant to be sarcastic).
[EDIT] - This post doesn't seem to say enough when I look back at it. Wanted to add this:
Seeing posts like this really excites me (and inspires me) about the future of web programming, and programming in general. Anyone that's excited about programming has to get excited about abstraction, and it doesn't get much more abstract that cross-coded/implemented virtualized systems like this. Even if you hate javascript.
Every step people take in blurring lines between systems like this should be exciting, given the large amount of abstraction that had to go into creating something like this.
