Exactly even with the same sized boxes users can request all sorts of
pages. Some much heavier on the CPU than others.
I just figured I could use SSH from the LB. ssh to each box as nobody
or a user with minimal access, and run and uptime and free and then
parse the outputs, and set the weights accordingly w/ ipvsadm
I guess I'll have to write it. I'll post what I script here, it should
be simple enuf to do.

No, even if you'are indentical box, customers can read differents
page. Some of them may heavy php/sql which implies a higher load
average than a simple static html file. (in the case of http load
balancing..)
Well, I think it should be interesting to devel a small application
running on real server which send the load average on the box to the
real server which adapt the weight automatically.
