When "RequestHandler.OnBeforeResourceLoad" is implemented, I can use Python's 
ZipFile.read() to get the bytes of the requested file.  That should produce a 
usable stream.  If not the results would need to be converted to a compatible 
stream.

Here's an example of zip file extraction.  Not a stream as will be needed for 
the callback, but a start.  
It only works with ZipCrypto encryption and not AES-256.  I have not yet 
figured out how to encrypt(save) with a password.

We already have a ready code in c++, so don't bother unless you can do the same 
in Python (AES encryption, decryption with password).

AES c++ library, very small only 2 files, easy to implement:
http://www.lomont.org/Software/Misc/AES/AES.php

An example code of how to use it can be found in WBEA, see also CEF forum link, 
code snippets are over there.

With Cython we can use C++ libraries easily, so that's not a big problem, but 
of course if you could do the same in Python then that would be great, as with 
c++ we have to compile a static library for each of the operating systems 
(currently only windows, but linux and mac are coming).

There are other libs in Python for encryption, and the built-in module ZLIB 
should be able to handle AES.  I'll look further into it and report back.

In CEF 3 the ResourceHandler API can be used instead of CefSchemeHandler.
