Hi All,
There might be a simpler way to make the OPP achieve even, or close to even
loads.
The small change here is that the OPP has to use thresholds to distribute
keys instead of centers. Every node should have a MIN and a MAX threshold. A
key gets inserted in a node x if MIN_x
MAX_(n-1), then
ited paper (Rhul's paper) and will also look at
the other ticket.

Just in case some one uses the equations on that page, there is a small
mathematical mistake. The exponent is missing a -ve sign, so the error rate
is : ( 1 - exp(-kn/m) )^k .
