I am in need of a protocol that allows something between freenet and cocaine auction. bonus points for pointers to existing software: imagine a network of nodes that store information, say a number of websites. the information is identical on all (mirrors). I'm looking for a way to insert information (new pages, updates...) in such a way that it is impossible to find out where the information was injected. i.e. one node is the "master node", but nobody except it knows who. only the master node can insert information. bonus problem: in case the master node fails, the protocol should allow for a pre-determined (by the master node) other node to take over. who the "successor" is should not be known to anyone except the master node and maybe the successor.
