Allow users to send arbitrary amounts of their karma points to other users.

This can be used for bets, and bounties as on StackExchange.

Note that (if unrestricted) this has an impact on the effectiveness of requirements like "must have karma >= K to upvote/downvote/submit". An unscrupulous user with multiple sockpuppets can pass karma from one to another, using each one while it has the karma.

There are lots of possible mitigations, but I've only thought of one that I like. Bad mitigations: undo user actions if karma drops below threshold (ugh), rate-limit karma transfers (probably not very effective), distinguish "organically acquired" from transferred karma and use the former for thresholds (ugly and confusing).

I think the right answer is to have a karma threshold for transfers. E.g., if K is the highest karma threshold anywhere in the system, say that for A to give karma to B both A's "final" and B's "initial" karma must be >= K.
