One other point. Themed pagerank would be pointless anyway because it's only half the time an outbound link is related to the source site. I normally link to sites that are not related to me in any way. Why would I send my customers to my competition?

The same applies to non-profit pages. There may be a couple of links on a page to similar pages, but most will be unrelated to the topic of the site. E.g. Embassy site gives links to currency converter, local airline, hospitals etc. Where is the theme?

The truth be told, the only theme that can be isolated is in the anchor text of the link. Google's already got that one sorted. The only thing they can do more is to "interpret" the keywords. This might do more harm than good though, as it would be easy for google to look pretty dumb by putting the wrong interpretation on the keywords.
