This looks good.  I can't see any obvious reason why there should be
a problem either. It will be hard to tell until someone actually tried to
implement the spec.

I'd love to see someone create a wrapper for zope.publisher that
provides a WSGI application.

I don't have time for more than an initial read.  The next step for me
would be to try to implement something, but I don't have time for that
either.

Given that people are creating server implementations for Twisted and
mod_python, there would be great value in having someone build an application
implementation for Zope and trying it out with Twisted and mod_python.
