	For a lighter alternative follow Quantafac's suggestion of building
a network of jails - many years ago I simulated a complete two site system
with two sets of database, middleware and web front end servers running at
each site on a single machine and used it to test all the failover
scenarios (including the cross coupled dual master failover database

	It went into production as two physical machines at each site, each
one running one copy of the stack in three jails.
