Yep, that was me. As I've said earlier (check out the thead starting at
http://www.in-addr.de/pipermail/lvs-users/2002-November/007264.html ), the
software sends server load information to the director to be inserted in to
the ipvs weighting tables.
I'm busy writing up the benchmarking results at the moment, and I'll post a
link to the paper (and software) soon. In summary: when the simulation
cluster is (intentionally) unbalanced, the feedback software sucessfully
evens the load between all servers.

This would be a simpler solution, as it could be done entirely on the
director.. Of course, your mileage will vary depending on how closely the
time taken reflects server 'health'
