Actually NTFS read and write is built in the base firmware, and NTFS filesystems will be mounted and used whenever they will be found, either internally or through USB.
The ntfs-3g-ntfsprogs package allows in addition NTFS creation and maintenance.
The issue with NTFS is that, as you pointed out, it is alien to linux, and there will probably be issues with file permissions and ownership.
Everything should be OK if those filesystems are merely used to serve files, as Alt-F does not runs from disk but from flash memory, using a linux filesystem, but I think that you will have issues if installing Alt-F packages on them.
