What about just using Samba as a front-end to a shared NFS backend? I
know that under Linux at least Samba and NFS can both ack locks due to
the "kernel oplocks" option.
Shouldn't that do what you want? Someone opens a file on Samba-Site1,
and the central NFS server locks it for the rest?
Obviously performance will be an issue as I assume you are talking about
sites being geographically separate. Neither NFS nor Samba/SMB perform
well over a WAN.
