Honestly I think this might end up being the mid-term solution.

For legitimate traffic it's not too onerous, and recognized users can easily have bypasses. For bulk traffic it's extremely costly, and can be scaled to make it more costly as abuse happens. Hashcash is a near-ideal corporate-bot combat system, and layers nicely with other techniques too.
