Answer 1

I think Fatelf (available at http://icculus.org/fatelf/ ) is what you are actually asking for, but it requires certain patches to kernel, glibc, gdb etc. So it's currently not for the faint of heart to use. It may be a reasonable burden for a developer to compile on a modified system, but it also requires client-side systems to be modified, too.
