It would be nice, but I'm not certain it's practical. I mean, if we embed
a Windows .exe in there, Windows is never going to be able to load it, I
presume.

That being said, I suppose there's no reason you _couldn't_ do that with
the existing FatELF format. Just add an OSABI for, say, Windows PE files
and embed one like anything else. Non-Windows platforms will ignore it
because it's the wrong OSABI. If something tried to process it as an ELF
file, it'll correctly believe it to be a corrupt file.

(Replace Windows with your favorite non-ELF platform if you like.)

This isn't really a goal of the project, but since you brought it up, it
IS actually feasible with the existing code and framework.
