+
+ <para><command>vfs_media_harmony</command> automatically redirects

+ directory to a client-specific version of the file. No
+ configuration beyond enabling the module is needed to get this
+ portion of its functionality working.</para>
+
+ <para>If Mac and Windows Avid clients will be accessing the same
+ folder, they should be given separate share definitions, with
+ hidden Mac files vetoed on the Windows share. See EXAMPLES.</para>
+
+ <para>To allow each client to control when the Avid application
+ refreshes their Avid databases, create files for each client
+ and each Avid media directory with the name
+ [avid_dir_name]_[client_ip_address]_[client_username].
+ To trigger Avid database refreshes, update the write time on
+ those files. See EXAMPLES.</para>

+ * Media Harmony is a Samba VFS module that allows multiple AVID
+ * clients to share media. Each client sees their own copy of the
+ * AVID msmMMOB.mdb and msmFMID.pmr files and Creating directories.
+ *
+ * Add this module to the vfs objects option in your Samba share
+ * configuration.
+ * eg.
+ *
+ * [avid_win]
+ * path = /video
+ * vfs objects = media_harmony
+ * ...
+ *
+ * It is recommended that you separate out Samba shares for Mac
+ * and Windows clients, and add the following options to the shares
+ * for Windows clients (NOTE: replace @ with *):
+ *
+ * veto files = /.DS_Store/._@/.Trash@/.Spotlight@/.hidden/.hotfiles@/.vol/
+ * delete veto files = yes
+ *
+ * This prevents hidden files from Mac clients interfering with Windows
+ * clients. If you find any more problem hidden files then add them to
+ * the list.
+ *
+ *
+ * Andrew Klaassen, 2012-03-14
+ * To prevent Avid clients from interrupting each other (via Avid's habit
+ * of launching a database refresh whenever it notices an mtime update
+ * on media directories, i.e. whenever one editor adds new material to a
+ * shared share), I've added code that causes stat information for anything
+ * directly under "Avid MediaFile/MXF" to be taken from
+ * dirname_clientaddr_clientuser if it exists. These files ~aren't~
+ * hidden, unlike the client-suffixed database files.
+ *
+ * For example, stat information for
+ * Avid MediaFiles/MXF/1
+ * will come from
+ * Avid MediaFiles/MXF/1_192.168.1.10_dave
+ * for dave working on 192.168.1.10, but will come from
+ * Avid MediaFile/MXF/1_192.168.1.11_susan
+ * for susan working on 192.168.1.11. If those alternate
+ * directories don't exist, the user will get the actual directory's stat
+ * info. When an editor wants to force a database refresh, they update
+ * the mtime on "their" file. This will cause Avid
+ * on that client to see an updated mtime for "Avid MediaFiles/MXF/1",
+ * which will trigger an Avid database refresh just for that editor.
+ *
+ *
+ * Notes:
+ * - This module is designed to work with AVID editing applications that
+ * look in the Avid MediaFiles or OMFI MediaFiles directory for media.
+ * It is not designed to work as expected in all circumstances for
+ * general use. For example: it is possibly to open client specific
+ * files such as msmMMOB.mdb_192.168.1.10_userx even though is doesn't
+ * show up in a directory listing.
