Yup, of course in my simulation I have a weighted polling queue and the servers
can remove themselves from the queue by using an invalid weight. (And of
course, it's only a simulation!)
As regards to LVS, I don't think it would be too tricky to implement a dynamic
round-robin like scheduler in which the candidate for the round robin can
invalidate themselves if they believe they are too heavily loaded.
The crux of what I am doing of course, which has already been brought up, is
trying to gauge 'load'.
