Correct, but to go from VLAN to VLAN there is a layer3 hop involved.  I 
don't believe it to be true if you have a single VLAN that clients and 
virtual servers in the same L2 domain cannot be load balanced.  I've 
personally tried this numerous times, and it's never worked.  Between 
VLAN's yes, but then that's not the same layer2 adjacency.  Paul stated 
that he has servers and clients (other servers) in the same VLAN/subnet 
that need to access the servers... which to the best of my knowledge, 
cannot work.

Maybe if you're doing two different VLAN's and briding them together, 
but that seems incredibly messy.
