The discussion about the various techniques for buffer overflow prevention is very interesting, but if the target is to prevent the security threats caused by buffer overflows, then one should look for an operating system base solution, since it is an OS issue to enforce the security. Solutions based on the control of system calls execution like systrace (http://www.citi.umich.edu/u/provos/systrace/) or remus (http://remus.sourceforge.net/) are just two possible examples of such approach.
