[Brian Turner]

Attempting "index, no follow" would be a rather antiquated way of approaching what is effectively utilised by a robots.txt file in trying to disallow bots from following links.

However, "follow" is the operative word here - the links almost certainly will still be recognised and counted. Thus I very much doubt that you could prevent PR leakage at all without modifying the actual outgoing links from the page, so that the links cannot be recognised as links. That's a key issue to channeling PR.
