This has always seemed silly to me. The kernel has had NTFS read-only support for years. The kernel source shipped by Fedora includes the source to the driver. However someone thought that it violates some rules if shipped in binary format, but not in source. Anyways, it took long enough.
Pretty soon, people will be able to access NTFS partitions out of the box, and if the NTFS-3G works as well as people claim then the read-write functionality should be there also. … I hope.
Update: For people looking for NTFS on Fedora.
