Most OS has already NTFS driver. And the Linux-NTFS code works on Linux, 
NetBSD, FreeBSD, DOS, Solaris, MacOS X, Windows and runs on about at least 
11 different platforms, big/little endian, 32/64 bit.

Depends on quality and richness of the functionality. NTFS is about 20 
times larger (250,000+ lines of code) than FAT but it's much more complex 
than that.

You could compare it with XFS or Reiser4. About a dozen people work on 
them full time for many years. Reiser4 is still not in the kernel.

And they don't have yet these features but it's on the work for Reiser4 for 
a year about, AFAIR.

People keep reporting trashed NTFS by Partition Magic, our code often 
catches positively inconsistent NTFS, corrupted by the Windows NTFS
driver, no really good feedback about Paragon's NTFS driver, so it seems
that basically nobody wrote a full-feature, reliable NTFS driver in the 
world yet.
