Okay, you can attack the swapping algorithm, yes. We need to figure out a way to secure it in the long run. It would be interesting to explore what the possibilities are for attacking it. One thing which is a given is that in 0.8 we will implement premix routing and in order to do this we will need to expose a large chunk of the local network topology. Maybe this could also be used for swap enforcement. > > Thomas -------------- next part -------------- A non-text attachment was scrubbed...
