That has to be the most paradoxical argument I've ever heard: "when
you use assembler you have the ability to not use assembler" :)

I found on the forum some discussion about crypting text and one guy
did make assembly implementation of crypting algorithm. He dynamically
generates mashine code and call that from python. Here are impressive
results http://www.daniweb.com/code/snippet216632-5.html
