I might be wrong, but I think the Apache processes share memory, so they 
cannot be distributed among several nodes. That's why HA-LVS TCP 
connection load balancing is recommended for Apache, rather than process 
load balancing.

If you're running OpenSSI 1.1, the Apache processes can be moved 
together as a thread group from one node to another. Not sure if this is 
useful for Apache, since the socket still remains on the old node.
