I want to load balance HTTP/HTTPS.  I don't want to go the two tiered route
if I don't have to.  According to the documentation and the diagram
http://www.linuxvirtualserver.org/VS-DRouting.html, VS-DR needs to have the
Real Servers on a local subnet.  I have two subnets, one can be local to the
VS but the other is physically and logically elsewhere on the planet.  Can
VS-DR handle this between the two sites?

The latter seems awfully complicated.

The first solution can be done with 1 layer using VS-DR and either
persistance or the fwmark solution that Ted Pavlic posted this weekend
(to keep clients on the same machine when they go from http to https).
