Really?  It's been a while since I looked at those objects, but it seems 
like it should be possible to subclass them so they delegate to 
Webware's request and response instead of reading out of 
stdin/stdout/environ.  Environ is already present, and I believe Zope's 
HTTPRequest.__init__ is close enough to Webware's HTTPRequest.__init__ 
that you could map the resulting internal data structures.  And Zope's 
HTTPResponse, if I remember, is pretty simple.

I don't know about traversal, but I don't know why it wouldn't be 
doable.  URLParser returns a Webware servlet, not a path to a file, so 
the wrapper only has to wrap the Zope object in a servlet.

That might be an interesting feature, i.e., to wrap the response in a 
stdout-like object, and serialize the request back into a stdin-like 
object, and rewrite a couple environmental variables to represent the 
new context.
