I just had a quick look at that article (I hadn't before). It's probably
possible to do something similar on other systems: In principle, you can
know the layout of an .so, and then manually load it. But, basically,
don't. While supporting Linux itself might not be too difficult (you can
use the libdl (or kernel?) sources as a reference, I expect), but
supporting multiple UNIX variants is almost certainly very, very difficult.

Maybe there are some actual experts around with a different view, but
I'd recommend, to load object code not directly accessible via the file
system, put it in the file system!
