I suggest, instead of using the stock "Factory", making a subclass of
it with buildProtocol implemented like so:

def buildProtocol(self, addr):
    p = Factory.buildProtocol(self, addr)
    self.connections.append(p)
    return p

Or similar (you'll have to define the 'connections' list yourself in
__init__). In the protocol's connectionLost, you could then remove the
protocol from that list.
