WLBS works fine, but it HAS to be setup on it's own VLAN with STP turned 
off on all ports. Use a crossover cable to connect that cluster VLAN to the 
rest of the network. We have this working for 100+ machines and it works 
great. Usually, we use a different switch - just to be safe. The WLBS NIC 
also must be different than the primary NIC in the machine.
