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 reasonable, IMHO. (Remember Bill Gate's famous statement "640 KB should be enough for everybody"? ;-) > Also, if you do a implementation from the public data in the headers, is > that code also under GPL? 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.
