Unless I missed some subtlety earlier in the conversation, yes you can :).

python 2.6's zipfile module can cope with a shebang line in a zip file just
fine, and since this is the first version of Python which supports this
feature, that means the following works just fine (tested on OS X and Linux):
$ echo '#!/usr/bin/python
> ' > header.txt
$ echo 'import sys; sys.stdout.write("Hello, world!\n")' > __main__.py
$ zip go.zip __main__.py
adding: __main__.py (deflated 2%)
$ cat header.txt go.zip > go.py
$ chmod a+x go.py
$ ./go.py
Hello, world!
This use-case was specifically mentioned on
<http://bugs.python.org/issue1739468>, too.
