Starting point of Syslinux (memdisk) is what I was looking for.  
    - kernel is "memdisk" and initrd is ISO image, so configuration is
      easy to maintain.
    - it finds the ISO -- you see dots filling the screen as ISO is
      loaded.
    - ISO boots -- you see the splash screen of ISO.
Then, it complains it can't find the live filesystem, the very image it
just loaded.

MultibootUSB.org extracts ISO, and puts the content into a partition.
This is not what I want.

I give up.  Thanks guys.
