you need re-training. You're out of date :-) You'll have to go off
for a 1 week refresher course to get your LVSCE again.

The sync demon (on the director) broadcasts the state of the connections.
You should (in theory) be able to run the sync demon in backup mode
on the realservers to pick up the connection table. The sync demon
on the realserver will lag a little (don't know how long) behind the
connection table on the active director, but it will be a lot faster
than ssh/ipvsadm. The backup sync demon(s) are supposed to be
close enough to the state of the active sync demon to handle a failover.
Horms has a new implementation of the sync demon, which he talked
about at LVS. If this looks a reasonable idea, then ask Horms
for his code (I don't know if it's released yet, it's being
done as part of his work).
I'd have a look at LVS-DR first. You can find the VIP from
`netstat -an` without all this mucking around
