Well, if you had a file system that would let you do something like
reserve some spare space in the front of the actual start of the
file for this sort of thing (think small offset stored in the FAT
and special I/O calls to jack with it) it would be a lot easier.
In practice, it doesn't seem to be a big enough problem to justify
the hacks, so AFAIK, nobody every bothered to build a file system
optimized for single or small byte insertions at the beginning of a
file. *shrug*

No problem.
