Yep - I have read it.

It should not be hard to port the example given in the paper to
Linux. Take a look at the man page for dlopen(). It describes how to
open (load), close (unload) a shared object in Linux. The function
similiar to Win32.Winbase.GetProcAddress on line 23 in the example, is
called dlsym() in Linux.

The technique using dlopen() and friends is used by fx. the web
browser Firefox to load plugins.
