No, just memory (or even address space rather than actual memory mostly).

Do you mean embedding the filename in whatever *2john outputs? If so,
this is appropriate for large files. I think we're doing it for RAR
already.
Or do you mean patching the loader to read binary files directly? This
is inconsistent with the current approach, although we might arrive at
it later, perhaps by introducing some per-format handler similar to
prepare() but intended for binary input files. This is not something
you should attempt now.
Thanks,
