 If the probability of the peer selection algorithm putting a node close to
 the beginning of the list were proportional to its storage capacity, then
 that would better tolerate grids with a wide range of node capacities.

 With a uniform selection probability, as at present, small-capacity nodes
 will be expected to receive many requests to store shares that they don't
 have room for, and to download shares that they don't have.
