Thanks for all your insight, Craig.

I'm going to look (at least a bit) into fixing rsync so that it can 
handle read-only files on a samba target. There's no reason it can't 
work, and I have an idea how it can be fixed.

Question about robocopy though. When it's used to copy from native NTFS 
to a samba share, do you know if all of the traditional attributes (not 
ACLs) are brought across as well?
