        It looks good to me. Balancing based on outbps can
also be a good option for NAT. I assume there is one side effect,
one server can accept more load in short time while its inbps are
still low. As alternative, a wrr algorithm with weights updated 
(frequently enough) based on inbps/outbps can better keep the
load according to the weights. But it depends on the content length per
connection, on the estimator's update period (isn't 2 seconds too
high for wlib) and only the traffic stats can make one happy :)
