Mr. Andreessen posted an update on this article which includes some examples, http://blog.pmarca.com/2007/10/open-social-scr.html

the following quote is from this article and I believe it should answer your question

"... You'll notice in those Ask A Ninja examples that the Flixster app is not as visually integrated as in the other examples. In a real production system, the Flixster app will pick up the styles of the parent page."
