[Samba] Need some explanation on Samba/NFS locks handle

I understand your point of view.
But, we do/can NOT want to modify our OS2 applications.
So, we have to keep OS2 deny mode method and migrate OS2 SMB clients 1 by 
1 to Linux NFS client with no loss of file integrity...
Then, we are thinking about modifying Samba server code to "emulate" deny 
modes with byte range locks....

Any idea about another way to resolve this point ?
