You can download a demo here:
  http://labs.adobe.com/downloads/cssregions.html
I tested the windows binary with wine. It needs to run from the 'bin' 
directory in the zip.
It is very impressive. The regions and wrapping together make many ODF layouts 
possible now.
Since it's based on webkit, the source code should be available too, i did not 
see the link to that though.

Cheers,
Jos
