I don't see the need for that on Linux: you can do the same thing already with a shell script.
In the example below, foo.zip contains foo.py.

martin@mira:~$ cat runzip.sh
#!/bin/sh
export PYTHONPATH=$0
exec python -c 'import foo;foo.main()'
# THE END

martin@mira:~$ cat runzip.sh foo.zip >bar
martin@mira:~$ chmod +x bar.zip
martin@mira:~$ ./bar
hello

So unless that adds a functionality that I'm missing, I'm -1 on this patch.
