I use a Win2000 Server box using Services For Macintosh and happily store Apple files natively on the NTFS disks.
The server will put the resource and finder information into two seperate NTFS streams ( :AFP_Resource and :AFP_AfpInfo ) so the technically there was no need for the ".sits". Note the icon you see from Windows explorer has nothing to do with the icon you see from a Macintosh mounting the shared volume.
I also have a binhex and unbinhex tool pair which lets me encode and decode HQX files happily onto the windows volume from the windows side of things by reading and writing the above mentioned streams, this allows me to copy Macintosh files into a standard format for putting on media that cannot cope with the streams.
