Easiest formula:

     number of files I'm responsible for
---------------------------------------------
  fraction of hashtable I'm responsible for

Not the most accurate number, but should be a reasonable guess, it's
easy to calculate, and works regardless of the number of peers.

Anyone who tries to defeat things could just wait until the hashing ends
and defeat it then, anyway - nothing new here.
