In the round robin dns setup once you get on a server you stay on that
server 
therfore your aspell files will be on the server you are on at all times.
It is 
not a true load balance were all processes are shared over a number of
servers 
but it tries to spread users over many servers.  The thinking is that if all

users use the service the same way one user is the same as any other and
would 
not overload a server with any more processes than any other user.
