FYI, I was thinking more of traditional voting in political systems, such as the UN security council where we are used to hearing that X voted for, Y voted against, and Z abstained (or something like that). I would consider it a "neutral" vote so it might be worth including in "x number of votes" info. And of course XP benefits and penalties should not apply and the XP penalty for too many downvotes should be unaffected. I'm curious as to why you think it should cost more than 1 vote? With that said, I'm not sure if it would really be worth the time to implement -- for me it would be more of a curiosity thing.
