NFS multipathing

I would like to see NFS multipathing.

Quite possibly this would work properly with only client side development. By that i mean that the NFS server almost certainly wouldnt know that its going on, except maybe with locking.

Essentially, the mount command might somehow be told that two servers:/exports are the same thing.

mount -o secondary="serverip2:/vol/export" serverip1:/vol/export /mnt/point
