xmlrpclib mapping method names in dictionary

You should generate an exception in _dispatch in response to an invalid
command name (right now you are returning None, which is not a valid
XML-RPC type). I'd solve the problem like this (not tested):

class ShellCommand:
	def __init__(self, command):
		self.command = command
	def do_command(self):
		# Are you sure that you want to readlines?
		return os.popen(self.command).readlines()


cmds={'ps':'ps -eaf',
       'df':'df -k',
       'uptime':'uptime',
       'who':'who',
       'last':'last',
       'iostat':'iostat',
       }

server = SimpleXMLRPCServer.SimpleXMLRPCServer(("localhost", 9000))
for name, command in cmds.items():
	server.register_function(ShellCommand(name).do_command, command)
server.serve_forever()

This way you don't have to use a custom dispatch method.
