So the problem with using interoperability as your prime driver is that other operating systems won't have implemented your LanyFS, and because of licensing issues, it will be very hard to get even a shareware distribution of LanyFS for Windows (because of licensing issues around Window's IFS SDK). In practice, the solution of using either FAT for most cases as the interchange format works well enough for most purposes. Granted it doesn't in the case of your example of a 6GB video file (which I'd probably transmit using a networking protocol, since a thumb drive would be really slow.) What I would do if I needed to transfer such a file, and I didn't have access to high speed networking, would be to use ext2, and then either use the ext2 FUSE driver with FUSE for Windows or Macintosh --- or, I would port the userspace e2tools package to the target OS, and use that to access the ext2 file ssytem. And I'd do that because the software is available today, right now, without having to figure out how to port LanyFS to the operating system. > There is a small niche which LanyFS tries to fit in.

That is *always* going to be easier than figuring out ahead of time which files you want, and then manually copying them onto a thumb drive, and then taking the thumb drive to the car.... Somehow I can't quite imagine your grandma manually copying files over using LanyFS. :-) I also seriously question the niche of people who want to use a thumb drive to transfer > 4GB files. Try it sometime and see what a painful user experience it is....
