I've read the MiniHowto and the UltraMonkey Tutorial. Something that I'm
not entirely clear on if I can do a direct routing setup with only using
one routable IP address (aka, the VIP).

In all the usual LVS setups, only the VIP is routable. The LVS is supposed to look like a single server to the client.

What I would like to do is to put the realservers on a DMZ with
non-routable addresses. And since I have two nics on the realservers,
can I configure the realserver nics plugged into the WAN switch with the
VIP? (arp_ignore of course). And  then I wouldn't need to do a lo:0,
would I ?

It used to work with the 2.0, 2.2 kernels. Noone has tried it since then (that I know about). It should work.
