I'm pretty certain that tar is completely network un-aware. That is,
tar can only access files that are either local or are provided locally
through a file-system (eg. NFS, Samba, AFS, etc.) mechanism.
So have you tried using Samba to make the "Windows shares" on your other
machines accessible to your Linux box? That would probably be the
easiest route for backups since tar could then treat the files on other
machines as if they existed locally.
