Majority vote for cancelling?
I think we should switch the cancellation vote to a simple majority rather than unanimous.
Had a scenario recently where someone dropped out of a 4 player game, so myself and one of the remaining players voted to cancel, not wanting to play a game where the balance was thrown off so much (it was only round one or two, iirc). But the last person refused to cancel the game, in essence holding our Karma hostage. Either we leave and take the Karma hit or we play through a horribly unbalanced, unfun game where one of the players dropped. I ended up just quitting out and taking the hit, which I only regret because this system punishes that act so hard.
An alternative proposal could be to eliminate the Karma penalty after one player drops - giving the other players a free out, if you will.
In either case, I don't see the problem with a majority vote and there are plenty of problems with the unanimous vote.
Imagine a 3-player game, where one person is winning by a large margin. The other two could vote to cancel under your scenario. Eliminating the Karma penalty after dropping makes much more sense in my opinion.
If someone else drops out, your score won't be negatively affected.
So you can just pass the remaining turns without worry. But maybe a way to drop out would be more explicit.
MasN is right, and the same problem could arise (though more rarely) in a 4p game.
I feel that Karma however is needed, it provides some protection from compulsive droppers.
The solution to the specific problem reported by FDB, at any rate, is simple, and it already exist. If a player drops and you don't want to continue playing, you simply have to pass each turn. You won't lose karma or ELO (because you don't lose ELO in games with dropped players), and you don't have to play the rest of the game.

I'm not sure it's that simple - having to press to decline power charge repeatedly can be a chore, and maybe not even possible. I've been dropped from one game because a slow player dragged it out beyond the expected time (to the next day even) and then dropped, and I simply wasn't available any more to press "Decline power" every 5 minutes - so I got dropped too.
Having a "I pass for the rest of the game" button in these situations (as coyotte suggests above) would be really appreciated.
Also an "accept all/decline all" option when it comes to charging power would help solve the problem and it'd be useful in general.
A "quit" button was just added, next to "Vote cancel", and it appears when a player dropped out. It allows you to quit without penalty.
