You might want to check out how dpkg actually unpacks the control.tar.gz,
if memory serves me it uses tar without chroot to do it, which means that
control.tar.gz could easially contain /bin/sh or something equally nasty..
So it is hardly a guaranteed safe action right now.
Of course that is fixable, Goswin's idea isn't.
