One of the long term goals of LVS is to move all the code to 
the FORWARDING chain. This way we'd remove the requirement 
for the VIP on the director. Source routing for LVS-NAT, 
which currently doesn't work, would be handled by the 
regular routing tables.

Horms has code where ip_vs() is in the PREROUTING chain 
(mentioned in

and last I talked to him about it, he was looking for people 
to test it.

Ludo also moved LVS to another spot

Ludo's code is linked from the HOWTO.

You might want to contact Horms off-line for his code. He's 
likely busy at the moment, as judging by the infrequency 
he's replying to the list.
