Tunable
  
  We want to be able to play with parameters:
  
   - Number of hops allowed for each search
   
- ``Broadness'' of searches (fan-out at each peer)
   
- Degree of randomness in query routing
   
- Maximum TTL of searches in the network
  
  We can conduct network-simulation experiments to determine optimal
  values of some or all parameters.
