I know it's an old thread, but once I get my LC III up (converting an LC II to LC III) I am going to try to re-package these files in .sit. I will have to track down an old form of Stuffit somewhere (possibly eBay) or use a trial version or something if it exists. I will package it as old as I can.
The server I have running does use NTFS, so it shouldn't be a problem, but I will see what I can do.
