One idea that I have been running through my head for awhile is a Tor like onion router that could be funded by a special cryptocurrency. This would mean each relay would get some amount of money for passing a packet on to the next relay. Ultimately this would solve two problems with Tor: speed (as it is paid there would likely be more relays with faster connection) and issues with spam (DOS over the network would cost a lot more.) Obviously it would suffer from some anonymity issues that would need to be solved as you are paying and it could be traced. I don't know if this idea would solve the issue in this case but I figured I would mention it.
