Wouldn't it be simpler to hack the name daemon to do the load balancing, so when they lookup 'www.xxx.yyy' it picks a machine and directs them to the IP for 'wwwX.xxx.yyy'? From that point on you dont care what they are doing. I know VMS can cluster like this, without a problem (through MultiNet). Sorry if this has already been discussed, I'm jumping into the discussion rather late .. -Brandon Gillespie-
