You don't have to hack BIND to do that, since it already supports
round-robin hostnames with multiple A records. What Cisco's
LocalDirector box does (and what others are proposing to do with a
FreeBSD box and ipfilter) is forward packets divert packets to
different hosts based on a least-recently-used cycle, or least-load
cycle, or whatever local policy you have. It will also automatically
remove a host from the pool if it is down or doesn't have a server
running. It's basically a proxy server with some extra smarts built
in.
