What is "native", really microprocessor executable binary ? How do you adapt 
to diversity?

Hum, "etc" is important here, CPython libraries makes Python power 
("batteries included"). And running such code on client side have 
*important* security concerns? I won't see people allowing automatically 
loaded Python scripts (or their binaries) execution on their system as is 
without a security layer.

Supporting features is not only parsing code, it's providing same execution 
semantic. And its a reason it would be more complicated to use exactly same 
execution kernel to run other languages.

You seem to start a new, potentially complex project (devil is in details), 
ignoring other works which already did same job:

Apart from ironpython, parrot, jython, already listed, you can look at:
 
Brython to run Python with a JavaScript/ECMAScript engine
	http://brython.info/

MicroPython to run Python on small embedded systems
	https://micropython.org/

Also look at https://wiki.python.org/moin/WebBrowserProgramming where there 
are many other projects of that kind.

You want Python on the web browser, try to produce asm.js code, you will 
benefit of all work done on JavaScript engines, and of security layers. 
But? you will have to rewrite the batteries into pure Python mixed with 
asm.js code, this is huge work.

Bon courage.
