That's great! Have you published it? If not, please consider doing so.

This is actually a lot of fun. Never did it on Linux, but Windows PE EXE files make similar tricks possible. Windows 95 in particular was very permissive. Using a (very primitive, by today's standards) hex editor I tried making the ".text" section begin halfway through the header and bang! ..it worked, a revelation of sorts. I imagine today's loaders may be a bit more strict because of security but I guess you can always make your own loader :)

There are no relevant security concerns, but they may require page alignment for efficient mapping.
