For things that should be static, but replicated (such as the netlogon
share), this sounds like the right solution.

You cannot safely replicate files between two CIFS servers, unless you
also manage the locks and share modes. A BDC is not a mirror of a PDC,
for file shares, only for the logon database. Clustered CIFS is *hard*,
see recent discussions on samba-technical.
