+Comply with the newly defined protocol on the web page.

+Various things need to done to comply with the newly defined protocol:
+ - use the compact encoding of contact information
+ - remove the originated time from the value storage
+ - add the token to find_node responses
+ - use the token in store_node requests
+ - standardize the error messages (especially for a bad token)

+When looking up values, DHT should return nodes and values.
+
+When a key has multiple values in the DHT, returning a stored value may not
+be sufficient, as then no more nodes can be contacted to get more stored
+values. Instead, return both the stored values and the list of closest
+nodes so that the peer doing the lookup can decide when to stop looking
+(when it has received enough values).
+
+Instead of returning both, a new method could be added, "lookup_value".
+This method will be like "get_value", except that every node will always
+return a list of nodes, as well as the number of values it has for that
+key. Once a querying node has found enough values (or all of them), then
+it would send the "get_value" method to the nodes that have the most
+values. The "get_value" query could also have a new parameter "number",
+which is the maximum number of values to return.

 Missing Kademlia implementation details are needed.
 
 The current implementation is missing some important features, mostly 
 focussed on storing values:
  - values need to be republished (every hour?)
- - original publishers need to republish values (every 24 hours)
- - when a new node is found that is closer to some values, replicate the 
-   values there without deleting them
- - when a value lookup succeeds, store the value in the closest node 
-   found that didn't have it
- - make the expiration time of a value exponentially inversely 
-   proportional to the number of nodes between the current node and the 
-   node closest to the value
