I'm personally not a fan of the idea of raw processing puzzles. Has anyone investigated network puzzles of some sort, like requiring clients to retrieve a key/signature from a 3rd party? For example: a DDoS vulnerable server requests clients first get some token signed by a trusted 3rd party capable of handling heavy load & filtering DDoSes better, then can use that signed token to connect to desired server.
