Why is it the wrong tool for the job? I read up a bit on asyncore, and see
it's supposedly a single threaded server. Is that part of the problem?
The way I see it, zope's got its own web server and framework that handles
HTTP requests; WebSockets initially connect over HTTP, before upgrading to a
WebSocket connection. If the 'upgrade' request was recognised by zope, then
couldn't it just forward the connection on to any WebSocket server? It
wouldn't even need to do the handshake, but a compatible proxy would no doubt
need to be implemented.

The dependencies of all other Python-based WebSocket implementations all
require a completely different application stack. Twisted, which autobahn
uses, looks very powerful for low-level networking and the such, but it's a
beast and I've never used it before, in favour of making templated web apps
with grok..
Also, wouldn't the front-end socket of autobahn conflict with any other
running HTTP server? Sure, I could set it up on an alternative port, and use a
front-end webserver to proxy requests appropriately, based on URL paths and
patterns, like I do now with grok and Apache. But that adds another two
complications, when it comes to initially setting up the server. Installation
instructions for potential users would become even more off-putting than they
already are.
The zope server already has a good system for URL parsing and dispatching.
Would zope.proxy be any good at proxying WebSocket requests based on the URL?

WebSockets hadn't been invented back then, but HTTP was always meant to be
bidirectional. Get with the times :b (jk)
So, I think I understand that zope might not be great for managing
simultaneous bidirectional traffic, which is basically a requirement of a
WebSocket server. Could it not be a good proxy either?
