MEMDISK is intended to be used for operating systems which don't have a
direct way to boot.  This looks to me as a way for Grub2 to access the
internals of an .iso image as if it was a disk.  This ought to be
possible to implement in some form with the multidisk option, but that's
separate from MEMDISK.

This should be independent from at least the Linux kernel.

So I'm not sure there is a question here that relates to Syslinux, but
if there is it would be great if you could restate it.

There is a multifs branch in the git repo already.  It probably needs to
be merged and synced with the master branch, though; but this is well
within the scope of what can be done using that kind things.
