What if adding a node shifted down-ring tokens less and less? If adding node N+1, it shifts the first N/2^x, the second N/2^2x, the third N/2^3x, etc, so that a fixed number of nodes are shifted, but the bump is smoothed out? Tokens stay 1:1. I'm talking out of my league here -- haven't actually run a cluster yet -- so probably a dumb idea. :-)
