Status of Incubator's Declarative UI?

[JAWspeak]

The Declarative UI from the google team would be great to have out
here, even if it's in an unfinished state. I'm sure lots of open
source developers would be happy to work on it and improve things. Is
there a way to check it out?

I didn't find it when checking out the incubator or gwt itself, but
hopefully I'm missing something.

Thanks in advance,
