Nowadays, flash cards of 1 GB or even larger are pretty much
standard. Therefore I think that a 256 MB file system limit
is not reasonable. A file size limit of 16 Mb is even less
(Remember Bill Gate's famous statement "640 KB should be
enough for everybody"? ;-)

No, I don't think so (but I'm not a lawyer). But he wrote
that he wanted "to port cramfw", not to do an implementation
of his own, which is a different thing. But maybe he really
meant the latter.
