Also, if you run a comment author authentication service (Blogger & MT 
both do) you could could give an option to not put "nofollow" on 
comments with authenticated authors (assuming you also have some blog 
owner policing of who is authenticated)

This is where VoteLinks come in. Though it was initially conceived in 
response to a publicity attack (say something outrageous so people link 
to it and it gains currency), it has clearer semantics than the 
'nofollow', and does just what you intend here.

Indeed. A possibly bigger case of search-engine stuffing are the 
'furniture' links that appear on blogs and other CMS-driven sites 
automatically as part of the site's structure - even if Google didn't 
own Blogger, the few million links to blogger.com via the 'I power 
blogger' required link would ensure its high PageRank. Such things are 
maybe a reasonable quid pro quo for the service provided, but they are 
not an explicit human-made link...
