Comment (by mikeperry):
Ok, I agree. It seems like simply closing circuits is not going to buy us
much here.
How about providing the ability for clients to migrate circuits to an
IP/RP? That way, if a client *should* rotate away from a node, it can.
Additionally, if a node goes down because of DoS or any byzantine reason,
this would mean that the circuit doesn't have to be destroyed. Basically,
we could do conflux (https://www.cypherpunks.ca/~iang/pubs/conflux-
pets.pdf) without the split-flow control stuff (at least not at first,
though I suspect that the flow control pieces will be useful against
congestion attacks).
