The reasons for two networks are

o you get two ports for the director to talk out of (twice 
the bandwidth)

o the inside and the outside are isolated traffic-wise, ie 
no-one on the outside gets to see traffic in the inside.

If you have other restraints that override these, then by 
all means use a one-network LVS.

no, but we'd be delighted to hear how you do it.
