That sounds like something you need to deal with on the application 
level. You can't balance NFS (or CIFS, or any similar system) "per request".

The closest to what you're asking for I can think of is something like 
WebDAV (http://en.wikipedia.org/wiki/WebDAV) on the servers, with davfs2 
(http://savannah.nongnu.org/projects/davfs2) on the clients. You could 
then put a load balancer between the clients and the servers, or use DNS 
based load balancing to achieve more even load distribution.
