Hm... Given that most infections these days are JavaScript based and
run in the browser, how does this provide any protection? I'm
presuming you're going to say that it doesn't but that there are other
use cases where it *does* provide protection; but most likely those
use cases are only relevant for Windows (since that's what most
attackers attack anyway).

Since this intefaces with the hardware, doesn't it require some kind
of cooperation from the Linux kernel? And wouldn't it be better if
Python was never allowed access to any of the protected resources in
the first place?

Where/what is Umit? (Google gives several meanings but it's unclear
which you might mean.)

You'd first have to tell us more about the security model. What is a
"secure application" and what does it protect against? And how?

This is better directed at python-ideas, so I've redirected this reply
there and Bcc'ed the python-dev list.
