First of all: Daniel Kowalski, you rock!
I'm running WP 3.0 Alpha as part of my research to WP as CMS. Tried the addon and it works solid. I only found a minor bug:
As my language is Dutch, I changed the german words. Pages is translated to Pagina's ; because useing the ' the addon gets bugged and won't show up. For all using these special characters, try to avoid them.
Also, i've got a layout question. Is it possible to use images just like the original idear (like apple.com)?
I'll try to tweak it myself aswell, result will be posted here.
