Greetings nameless-and-frustrated Twisted beginner!  Have a look at the
echoclient.py example, which you can download here:

http://twistedmatrix.com/projects/core/documentation/examples/index.html

Essentially you also need to create an EchoFactory and set it to run within
a reactor (notice that your server example already does this).

Hope that helps,

~Adam
