that is the open source version of exfat for linux/unix/bsd ect.
it uses the FUSE filesystem driver and has actually been around in mainstream linux distro's for quite some time so I'm not sure what copyright issues you are referring to, could you please explain?
well perhaps it would be a good idea to add the FUSE support into the kernel so people who need different filesystem support can then install the required FUSE modules in the userspace?
