Joe:
The servers will be in datacenters that I lease space from.
It looks like I will need cooperation from both of those
datacenters to make this work. I am not sure they would
be willing to do that.
Is this something datacenters would normally work with
me on or is it beyond the norm?
Thanks,
Neil

I assume you have two machines, each being a director and
realserver. It's Horms two machine setup but the machines
are in different locations, on different networks.
It's a standard setup except that you're going to have to
handle the routing yourself. If you can't move the VIP
between locations (each location will have different network
blocks), then you'll have to failover by changing the DNS
entries (slow, can take days). So you'll need the two sites
to cooperate (failover via the routing protocal which will
take 30secs or so) and both sites will need to be able to
take the VIP. Failover between different sites uses this (or
similar mechanisms) and is a pretty normal operation.
It's all routing - nothing to do with the LVS layer.
