This support was removed as it really has to be done kernel-side, but as to the state of integration now you'd have to ask Alexandre or Mike I suspect.

I have an app that wants to read from \server\directory\file.ini and I don't have an easy way of changing this, so I want to tell wine that \server\directory is available in /mnt/smb/server/directory. Is this possible? What do I need to do?
If you try to read from a path starting "\." in Wine (in some versions), you'll get a message saying something like "Fixme: UNC name (%s) not supported.", but there is basic support for Wine to read from a file directly over an SMB link for paths that start with "\" up until Wine-20040505. It identifies itself as a WfW server and doesn't attempt to provide a username or password, as far as I can tell. It looks like the relevant functions were deleted before 20040615.
In principle, Wine could probably provide UNC-name support by calling 'smbclient', or by parsing /etc/mtab for 'smbfs' mountpoints and trying to access them like any other file. Another alternative would be a configuration-file override to alias an arbitrary UNC path as some file, just like the old [Drive X] mappings.
In your case, would it be acceptable to have a local, static copy of the .ini file, and just point Wine at that somehow?
(Forwarding to the developer's list, since it looks like this is a useful feature that was removed because no one was finishing it.)
