Well, http://en.wikipedia.org/wiki/NTFS#Linux lists two commercial drivers:

1. Tuxera NTFS: High-performance read/write commercial kernel driver,
mainly targeted for embedded devices from Tuxera, which also develops
the open source NTFS-3G driver.

2. NTFS for Linux: A commercial driver with full read/write support is
available as free and non-free download(s) for Desktop and Embedded
Linux systems from Paragon Software Group.

Which one do you mean? Not that I can really use anyone, but it is worrying
that Tuxera maintains both NTFS-3G and a commercial version.
