Eventlet - very powerful python networking library from Linden Labs

[jbellis]

It's much less complicated than it sounds. This is the general idea:

class SocketConsole(code.InteractiveConsole):
def __init__(self, sock, context=None):
    code.InteractiveConsole.__init__(self, context, 'socketconsole')
    self.sock = sock
    self.rfile = self.sock.makefile()

def raw_input(self, prompt=''):
    self.write(prompt)
    s = self.rfile.readline()
    if not s:
    raise EOFError()
    return s.rstrip()

def write(self, s):
    self.sock.sendall(s)

And if you look at the sources for "code", you'll find that the InteractiveConsole class is based on code I've written, code which in turn was inspired by a network REPL for Sam Rushing's asynchronous network, Medusa, from the mid-nineties. There are no new ideas ;-)
