It's an interesting thought! There have been cases where I could not attribute PR going up and this could be it, however looking at a lot of the posts, I would have to agree with some of them that state that this would be way to easy to manipulate by spam farms with multiple IPs. Google definitely tracks from a quality perspective, but if they are truly utilizing this this to influence PR, then this poses many potential challenges...
