Take look at twisted.internet.stdio.StandardIO.

I'm new to this twisted stuff, so no doubt I've gotten this a bit  
wrong... but:

But, the act of listening is primarily about waiting for a new  
connection etc.; since standard io is already connected it doesn't  
quite make sense to listen for it.

When a listener L awakens for a new connection it cobbles together the  
plumbing necessary to manage the connection.  That plumbing will  
invoke the methods of an object C responsible for handling the  
connection.  The listener L creates the object P, one for each  
connection, by via the factory object F it was given when L was  
created.  It is the responsibility of C to implement protocol  
appropriate to the connection.

What twisted.internet.stdio.StandardIO provides is a very simple  
protocol for standard IO.
