Twisted is a tcp/udp[/ssl] framework, Tornado is an http one.

In other word, with Twisted, you can write http, ftp, smtp, ... and your are free to write your own protocol.

Well, twisted is an async framework, and that's the important thing. Back in the day I actually wrote a Twisted protocol to send/receive SMS messages from a modem over serial. In total the code was like 100 LOC. That's how flexible, well-organized it is.
