This technique looks feasible to me, except:

This really should be (also untested):

class DroppingHTTPFactory(http.HTTPFactory):

    protocol = DroppingHTTPChannel

    def startFactory(self):
        http.HTTPFactory.startFactory(self)
        self.currentConnections = []

    def stopFactory(self):
        http.HTTPFactory.stopFactory(self)
        for p in self.currentConnections:
            p.transport.loseConnection()

So that you can have multiple DroppingHTTPFactories without them interfering
with each other.
