The documentation should be amended as follows:

Running the following commands creates a server for a single shared
queue which remote clients can access:

>>> from multiprocessing.managers import BaseManager
>>> import Queue
>>> queue = Queue.Queue()
>>> class QueueManager(BaseManager): pass
...
>>> QueueManager.register('getQueue', callable=lambda:queue)
>>> m = QueueManager(address=('', 50000), authkey='abracadabra')
>>> s = m.get_server()
>>> s.serve_forever()

One client can access the server as follows:

>>> from multiprocessing.managers import BaseManager
>>> class QueueManager(BaseManager): pass
...
>>> QueueManager.register('getQueue')
>>> m = QueueManager(address=('localhost', 50000), authkey='abracadabra')
>>> m.connect()
>>> q = m.getQueue()
>>> q.put('hello')

Another client can also use it:

>>> from multiprocessing.managers import BaseManager
>>> class QueueManager(BaseManager): pass
...
>>> QueueManager.register('getQueue')
>>> m = QueueManager(address=('localhost', 50000), authkey='abracadabra')
>>> m.connect()
>>> q = m.getQueue()
>>> q.get()
