Multi User Environment

i want to create a multi user environment between several users that allows them to chat and watch the same environment together.
i tried this code from vizard reference but it did not work!
Server:
Code:
import viz
import viznet
viz.go()
viz.clearcolor(.2,.2,.4)

viz.MainView.setPosition(70,45,-60)
viz.MainView.lookat(0,0,10)

objectList = ['duck.wrl','logo.wrl','vcc_male.cfg','vcc_female.cfg']
maze = viz.add('tankmaze.wrl')
objects = {}

UPDATE = viznet.id('update')
CLIENT_DISCONNECTED = viznet.id('client_disconnected')
CHAT = viznet.id('chat')

viznet.server.start(port_in=14950,port_out=14951)

def onStartClient(e):
    print '** Client joined:',e.sender
viz.callback(viznet.CLIENT_CONNECT_EVENT,onStartClient)

def onStopClient(e):
    print '** Client left:',e.sender
    viznet.server.send(CLIENT_DISCONNECTED,client=e.sender) # Alert other clients
    objects[e.sender].remove() # Remove object from our map
    del objects[e.sender] # Delete user from array
viz.callback(viznet.CLIENT_DISCONNECT_EVENT,onStopClient)

def update(e):
    try:
        objects[e.sender].setPosition(e.pos)
        objects[e.sender].setEuler(e.ori)
    except KeyError: # If key doesn't exist add the user's object
        objects[e.sender] = viz.add(objectList[e.object],scale=[2,2,2],pos=e.pos,euler=e.ori)
        objects[e.sender].tooltip = e.sender # Sets the tool tip for this object
viz.callback(UPDATE,update)

# Tool Tip
import viztip
tth = viztip.ToolTip()
tth.start()
tth.setDelay(0)

# Chat Stuff
def updateChat(msg): # Function to update the chat display
    text.message('\n'.join(text.getMessage().split('\n')[1:])+'\n'+msg)

text = viz.addText('\n\n\n\n',viz.SCREEN) # Add to screen
text.alignment(viz.TEXT_LEFT_BOTTOM)
text.fontSize(25)
text.setPosition(.05,.08)

input = viz.addText('> _',viz.SCREEN) # Add to screen
input.fontSize(25);
input.setPosition(.032,.05)
input.visible(0) # We only want visible when in type mode

def onChat(e): # Update the message display
    updateChat(e.client+': '+e.chat)
viz.callback(CHAT,onChat)

talking = False
def onKeyDown(key):
    global talking
    if key == 'y' and not talking: # Start talking mode
        talking = True
        input.message('> _')
        input.visible(1)
    elif key == viz.KEY_ESCAPE and talking: # Exit talking mode
        talking = False
        input.visible(0)
        return True
    elif talking and key == viz.KEY_RETURN: # Send message
        talking = False
        viznet.server.send(CHAT,client='SERVER',chat=input.getMessage()[2:-1])
        input.visible(0)
        # Update display with our message
        updateChat('SERVER'+': '+input.getMessage()[2:-1])
    elif talking and key == viz.KEY_BACKSPACE: # Delete a character
        if len(input.getMessage()) > 3:
            input.message(input.getMessage()[:-2]+'_')
    elif len(key) > 1: # Handle special keys
        return False
    elif talking and 32 <= ord(key) <= 126: # Input message
        input.message(input.getMessage()[:-1]+key+'_')
viz.callback(viz.KEYDOWN_EVENT,onKeyDown,priority=-6)
Client:
Code:
import viz
import viznet
import vizinfo
viz.go()
viz.clearcolor(.2,.2,.4)
maze = viz.add('tankmaze.wrl')
objects = {}

SEND_UPDATE_TIMER = 1

CHAT = viznet.id('chat')

SERVER_NAME=viz.input('Enter Server Name')
while not viznet.client.connect(SERVER_NAME,port_in=14951,port_out=14950):
    if viz.ask('Could not connect to ' + SERVER_NAME + ' would you like to try another?'):
        SERVER_NAME=viz.input('Enter Server Name')
    else:
        viz.quit()
        break

objectList = ['duck.wrl','logo.wrl','male.cfg','vcc_female.cfg']
obj_choice=viz.choose('Connected. Select your character',objectList)

def update(e):
    if e.client != viz.getComputerName():
        try:
            objects[e.client].setPosition(e.pos)
            objects[e.client].setEuler(e.ori)
        except KeyError:
            objects[e.client] = viz.add(objectList[e.object],scale=[2,2,2],pos=e.pos,euler=e.ori)
            objects[e.client].tooltip = e.client
viz.callback(UPDATE,update)

def client_disconnected(e):
    objects[e.client].remove()
    del objects[e.client]
viz.callback(CLIENT_DISCONNECTED,client_disconnected)

def onStopServer(e):
    print 'Disconnected from server'
    viz.quit()
viz.callback(viznet.SERVER_DISCONNECT_EVENT,onStopServer)

import viztip
tth = viztip.ToolTip()
tth.start()
tth.setDelay(0)

def updateChat(msg):
    text.message('\n'.join(text.getMessage().split('\n')[1:])+'\n'+msg)

text = viz.addText('\n\n\n\n',viz.SCREEN)
text.alignment(viz.TEXT_LEFT_BOTTOM)
text.fontSize(25)
text.setPosition(.05,.08)

input = viz.addText('> _',viz.SCREEN)
input.fontSize(25)
input.setPosition(.032,.05)
input.visible(0)

def onChat(e):
    updateChat(e.client+': '+e.chat)
viz.callback(CHAT,onChat)

talking = False
def onKeyDown(key):
    global talking
    if key == 'y' and not talking:
        talking = True
        input.message('> _')
        input.visible(1)
    elif key == viz.KEY_ESCAPE and talking:
        talking = False
        input.visible(0)
        return True
    elif talking and key == viz.KEY_RETURN:
        talking = False
        viznet.client.sendAll(CHAT,client=viz.getComputerName(),chat=input.getMessage()[2:-1])
        input.visible(0)
    elif talking and key == viz.KEY_BACKSPACE:
        if len(input.getMessage()) > 3:
            input.message(input.getMessage()[:-2]+'_')
    elif len(key) > 1:
        return False
    elif talking and 32 <= ord(key) <= 126:
        input.message(input.getMessage()[:-1]+key+'_')
viz.callback(viz.KEYDOWN_EVENT,onKeyDown,priority=-6)
any suggestions?
