Crypto stuff may be "cool", but something that fits into the L1 cache
doesn't qualify as a real application, IMHO :)  Besides that, many crypto
algorithms can be done better (and faster) in dedicated hardware.

What's a 64-bit CPU good for, compared to a 32-bit one? It's not
necessarily faster, but it can handle large working sets. Therefore
I'd rather focus on scientific applications, databases and so on.

Huh? No difficulty?
