I try to avoid re-exporting NFS mounts!
And yes, I also prefer few (!) big file servers ...

But this is common practice:
Very few of our user know, where one of the 100 (logical) disks reside.
They use one of the few samba servers and follow symbolic links (to auto
mounted nfs disks).
And I prefer to be able to move disk space, without the user knowing
essentially, where the disks are really installed.

So, oplocks with samba and nfs should work reasonably.
