Btw, this is also going to be a VM and performance issue some time in the future. Tgere are already CPU's that would _love_ to have 64kB pages etc, and as such a filesystem that doesn't play with the old silly "everthing is a block" rules would be much appreciated with the kind of people who have multi-gigabyte files and want to read in big chunks at a time.
So either you have a simple block-based filesystem (current ext2, no extents, no crapola), or you decide to do it over. Don't do some half-way thing, please.
