Umm, I just tested this, and it doesn't work :/ I guess b/c storeio
claims that it is a character device:

% ls -l /tmp/hello.unzipped
crwxr-xr-x 1 teythoon teythoon 0, 0 Aug 29 13:01 /tmp/hello.unzipped
% /tmp/hello.unzipped
zsh: permission denied: /tmp/hello.unzipped
% /lib/ld.so.1 /tmp/hello.unzipped
/tmp/hello.unzipped: Must be started as a translator
