jt - Where does the session stuff reside?  At present I'm thinking about 
making a san cluster with Opencms using either NFS or GFS on the back 
end.  It *appears* to be working.  Basically I have the webapps 
directory on a SAN and the servers all read from it.  Anyone see any 
problems with this?
