Then, at the worst case, twisted's wsgi server can handle this sensibly 
and process whatever is passed to .log in such a way that it can go to 
its own logging.

logging isn't a particularly advanced feature from my perspective.

I don't know what echo_pool is.

If you *really* wanted that to go to the front-end wsgi servers log (I'd 
just log it to its own log...) then I'd write a proxy object that handed 
calls off to whatever the current wsgi environ is or bitch if one wasn't 
available.
