Yes, this depends on RoutesMiddleware being above it in the WSGI stack --
which nova.wsgi.Router provides.  WSGIMiddleware provides the dispatch --
when you call it, it looks at the data from RoutesMiddleware in environ and
calls the proper action method on self.

A controller would follow the standard REST syntax that map.resource()
expects, e.g.

class ServerController(WSGIController):
  def index(self):
    # return a list of servers
  def show(self, id):
    # return server <id>
  def delete(self, id):
    # delete server <id>
  # etc

I expect I'll make cerberus's rackspace.controllers.BaseController inherit
from WSGIController to provide helper methods, e.g. to format RS API Faults.
