The python is quite fine at doing the TCP indeed, muXTCP is the proof. Being implemented around Twisted, it actually allows you to fiddle with low-level TCP stuff, while e.g. offloading the SSL to the existing stack. It saved my bacon a few times when I wanted to reproduce a complicated network breakage scenarios. https://www.youtube.com/watch?v=BEAKtqiL0nM https://www.youtube.com/watch?v=BEAKtqiL0nM - Video about muXTCP from 22C3 https://github.com/enki/muXTCP https://github.com/enki/muXTCP - github repo with it.
