Lively - Squeak for Javascript?

Dan Ingalls gave a really interesting presentation about his work on Lively. You can see the video here.
I have been following Lively for a while - as a side point, running it in Safari makes a heck of a difference to performance (not sure whether that also applies to Safari on a PC). You definitely don't want to judge the product based on Firefox.

Anyway, what really struck me about the video was the way Dan could execute javascript in the environment. Anyone who as played with Squeak will be immediately struck by the similarities. In fact, when you dig down into the code, the whole object model looks amazingly similar. I am going to have to find the time to play with this!
