Does AFR over Unify not support your requirements?  It does provide a 
level of load balancing for AFR connections.  The main drawback is that 
files are stored somewhat non-contiguously on the disks (each server is 
part of two AFR's, where it's master AFR sub-volume for some of the 
files and slave for the rest).
