When I get time that is certainly one thing that will be an optional feature. MY idea is to measure the current buffered queue length (there is such a thing) - shift by some metric specifyable per next-hop and round-robins the group of the same and smallest number. If the metric is 0, it presets the result of the calc to zero. If all metrics are zero it by inference turns off the load-balancing. This may be coarse, but I'm not sure you'd need finer control. I don't know when I'd do it though - work got real busy recently (*big international lines take a lot of engineering just in person-to- telco time alone - sigh.)
