The to be released NTFS 2.0.7 for 2.6 kernel adds support for exporting
via NFS.  (-:  Unfortunately last week the hd at my computer at work blew
up so I didn't get round to doing my final testing so I haven't officially
released 2.0.7 yet but hopefully I will release it next week.  Assuming
2.4 now uses the same mechanism for exporting via NFS (I am not sure if
the 2.6 changes were backported or not) it will be easy to update the NTFS
backport with this feature.

Yes, most definitely we have no intention of implementing that feature in
the new driver! (-:
