Ok I'm going to fork this email into two topics.
1) What could an ISP do years down the road to protect us from floods.
2) What can we do now by clustering.

This email will be for number 2.

:-).  Everyone plays the patsy part of the time.  Let's forget about bootstraping for a second and
just imagine the final status.  Let's say you're in charge of a node in a DHT with 10 neighbors,
and you have 10 machines in your trusted cluster.  The niehboring clusters each have a different
IP of your cluster, and you only have one of each thiers.  Cluster to cluster communication can
only happen between the two ambasidors.

Now if one of of the niehboring clusters is evil, they could flood your ambasidor.  Suddenly your
ambasidor to Spain mysteriously disappears!  Well don't talk to Spain any more.  The other nine of
your neighbors can still route across you and use the remaining 90% of your storage.


The point of the GOT design is to limit the number of neighbors that could potentially be evil. 
This allows a cluster with a limited number of IPs to keep some of them safe.

I hope we're seeing the same picture now.
