In a nutshell, here's what we've done to solve this.  By taking advantage of
the http_proxy protocol, we can insert little mini-servers in between the
browser and the real servers.  For the most part, these little mini-servers
(okay, call them agents if you really want) just pass the request/response
stream between the browser and servers.  However, they can also filter,
modify, and take external actions based on what they see in the stream.  In
addition we have a browser prototyping testbed into which we've
incorporated a communications channel that the agents can use to inform or
control the browser.
