Sounds to me like a Tor wannabe, and will likely have the same issue as Tor: you need a whole bloody lot of nodes for the anonymity to be effective... and what is the incentive of running a node 24/7?

Something like DarkCoin masternodes, that get subsidy from the network for just being up, is needed IMHO to ensure that there are enough active nodes on a crypto network. DarkCoin ties the subsidy to mixing and holding enough funds however, so that's not ideal.

Ideal would be that anyone could run a full node and get a subsidy based on your uptime, transactions forwarded, etc. so people are incentivized to keep nodes running, and then *when* you have a solid network of nodes, you can devise IP anonymity protocols that leverage it.

Otherwise IMHO it's like putting the proverbial horse in front of the cart. :/
