Similar to that which is used on bodybuilding.com. Numbered reputation points, where every 1000 points given is equal to 1 point that will show next to your name. And when you rep or neg someone, you give/take the amount of points next to your name.
So if my rep power is 5000 and I rep someone who's rep power is 45, his rep power will go up to 50. If I neg him, his rep power goes to 40. If he reps me, then I get 45 points added to mine and am .045 closer to getting another rep power point.
It's a good system to have, honestly.
edit - Use your brains, people - if you even have one. Alts would have no effect on this system. Jesus christ....

I feel it wouldn't fit well.
