Poolcasting

Sachim's original intent was to add a pool command that would tinkle a willing DNS server, parse what came back and prune the population for the three survivors. Code to prune the survivors and manage refresh is already done for manycast and would be easy to use with pool as well. I'm not sure he finished the code or what shape it is in now.

The manycast code wasn't easy. The trick is to age the population after acquisition at a rate corresponding to whether a candidate is the system peer, among the survivors or not. Also considered is whether the stratum is below the floor or above the ceiling, which is useful to modulate the scheme, like protect the primary servers, etc.
