Sorry, NFS simply won't work with the model of operation you've described.

There is no way to do fallback to a secondary NFS server if the primary goes 
down when using read/write shares, nor does there exist any way to push the 
changes made to a secondary fileserver back to the primary, even if you could 
convince the clients to fail-over in the first place.

Maybe Samba/CIFS would come closer to what you want, or else WebDAV over HTTP?
