well, your above example would work, at least to a certain point, if you
let wget write its output to stdout:

#+begin_src sh :mkdir yes :dir "/tmp" :results file :file "crackzor_1.0.c.gz"
wget -c "http://ben.akrin.com/crackzor/crackzor_1.0.c.gz"; -O-
#+end_src

But I don't now know how to get the encoding right (I think that's the
problem). The zip file contains rubbish. What I would do instead is
something like this: 

#+begin_src sh :mkdir yes :dir "/tmp" :results raw :var fn="crackzor_1.0.c.gz"
/usr/bin/wget -c "http://ben.akrin.com/crackzor/${fn}";
echo "[[file:/tmp/${fn}]]"
#+end_src
