It's not a goal of mine, but I suppose you could have an ELF OSABI for it.

I don't think it changes the FatELF kernel patch at all. I don't know much
about ANDF, but you'd probably just want to set the ELF "interpreter" to
something other than and do this all in userspace, and maybe add a
change to elf_check_arch() to approve ANDF binaries...or something.

To me, ANDF is interesting in an academic sense, but not enough to spend
effort on it. YMMV. :)
