There is some tight coupling in cfengine between ip address and hostname
as returned by the system and reverse dns lookup.  Problems in these
areas, as with dual-homed hosts, can often be dealt with by using
BindToAddress or SkipIdentify.  But wanting to use the same ip on
different hosts is pretty unusual.  I'd ask WHY you want to do this,
when you said both hosts also have fixed addresses, in addition to the
'floating' vip.  I have a hard time imagining how this would work.  For
one example, you would be limited to running cfagent on one box or the
other, never both at the same time, never on a fixed schedule.
