Totally agree about more general solution.

That does not change anything, but just out of curiosity some
calculations were made: the number of atoms in the graphite of a
pencil is < 2^72,

http://www.madsci.org/posts/archives/oct98/905633072.As.r.html

so the storage providing capacity to hold files with 128-bit offset
would have to contain at least as many atoms as 8*2^56 = 2^59 pencil
leads ! Hundreds of tons of material that should be. And this is with
just 1 atom per bit of information. Seems a bit too much for any
conceivable technology... What FS would need to provide support for
such capacities ?
