This wouldn't work under the current setup, for example, we don't even
write the contents of the sh code block to a temporary file, so $0
wouldn't really mean anything... or actually, this would just return the
file-name of the shell used to evaluate the code block, e.g.,

#+begin_src sh
  echo $0
#+end_src

#+results:
: sh

Not currently, however if there is enough interest, it wouldn't be too
hard to add a :cmdline header argument to shell scripts, which would
result in the code block body being written to a temporary file, then
called with the supplied :cmdline arguments.

Yes, see http://orgmode.org/manual/Buffer_002dwide-header-arguments.html
