If this transport is implemented in terms of other protocols, it doesn't
have to be a reactor method. For example, lets say you write a SOCKSv4
transport; the way users would use it is probably:

mySocksProxy = SOCKSProxy('myproxy.example.com', 9999)
mySocksProxy.listenTCP(8080, SomeFactory())

Even if it requires registering file descriptors, you don't *have* to
add reactor.* methods (see e.g. twisted.internet.stdio).
