Could you please give me the equivalent on CIFS?

I have never worked with it.

As regarding NFS any advice in what to look for "when testing heavily"?

Have you tried using the CIFS vfs instead of smbfs?

Just a guess, but it may be worth trying.  If the Windows clients are 
seeing and respecting the locks then I have to assume that Samba is 
handling them correctly.  The different piece, then, is the client on
Linux side.

Another test worth trying would be to mount the directory on the Linux
clients using NFS instead of SMB.  I'd test that configuration heavily 
before going live with it, but it would provide some interesting
