Last week at TPAC, I put together a faked "shadow DOM" proof of concept for 
the PFWG face-to-face meeting. I got a chance to work out the remaining 
bugs this morning, and promised Rich and Frank I'd send it to the list. The 
zip includes the demo as well as a copy of the Prototype JavaScript library 
that I used for event abstraction.

The demo was tested and works on Mac OS X 10.6 Snow Leopard, with Safari 
and a WebKit nightly. The WebKit nightly will provide a slightly better 
experience due to recent implementation of the WAI-ARIA presentation role. 
Keyboard access works in Firefox (tested v3.5.5), but Firefox doesn't yet 
have AX API support, so I had no way to test the accessibility. That said, 
I expect it will work as intended in Firefox on Windows.

Please view the comments in the HTML, CSS, and JavaScript for specifics on 
how it works now and is intended to work.

James Craig
