     6   Actually I2P doesn't use peers from the same /16 in the same tunnel. Since your attack doesn't require two attackers in the same tunnel, the /16 restriction may not be relevant here.

    11   The I2P network is still relatively small but is growing quickly. How about a prediction or sensitivity analysis for a network 10X, 100X larger?
     14  The I2P network is still relatively small but is growing quickly. How about a prediction or sensitivity analysis for a network 10X, 100X larger? The analysis starts with "a" monitor peers out of the victim's fast pool of 30 peers. There's no analysis or discussion of how many monitor peers of a given bandwidth you need in the entire network to attain the number "a" in the victim's fast tier.
     15
     16  In fact, most fast peers are from a Class "O" (greater than 128 KBytes/sec) group of routers and those are about 20% of the network - so there's perhaps 400 peers that could potentially be in the fast group in today's network of 2000 - 3000 routers.
     17
     18  So isn't this really about an adversary taking over a large proportion of the entire network, or at least of the network's fast routers? Is I2P any more vulnerable at X % hostile peers compared to other networks?
