(Breaking the conversation below, because scrolling so far into comment section annoys me)

Tipler's idea has one hole - when universe collapses, inner gravitational force rises to infinity, causing slow down of passage of time. I'm pretty sure speed at which it will happen will eventually overcome benefits from small distances between parts.

Also, pretty obvious thing, it will create black hole. Unless we find out way to fish out information from computer which won't get crushed in singularity, no chance for Zeno's machine.
