 Somebody asked me if there is any way to have a real server and director
share the same host.  It seems to me this would be impossible, since a
NAT to the same host doesn't seem to make sense, and an ICMP redirect to
the same host doesn't make sense.  I don't know about tunnelling, but
that probably doesn't make any sense either.  But as I got to thinking
about it, I started wondering if there was any way to do this using
multiple interfaces and some kind of convoluted configuration.
The rational is that a user has a service they want to failover, and they
go to thinking that since they have two systems, maybe they could do some
load balancing too.
