I would disagree with your complaints about NTFS security.  NTFS security is
far more versatile and useful than Unix file system security (which is
really quite primitive and actually very difficult to use for anything more
complex than keeping people out of each other's home directories).
Admittedly, IIS has problems, but you should be able to create a write-only
upload directory in IIS by allowing write and denying read in IIS, and
setting appropriate NTFS permissions for the IUSR_* account.  (Caveat: I've
never tried this.)
