Not sure whats going on in your code. Must be some bug somewhere that I'm not getting.

This example I worked up does what you want to do (I think):

import viz
import vizact
viz.go()

IS_SERVER = True #change me to False for client
SERVER_NAME = 'DEV8.hq.worldviz.com' #for client, set to network name or IP of server 

import viznet
UPDATE = viznet.id('update')
OTHER_EVENT = viznet.id('OTHER_EVENT')

if IS_SERVER:
	viznet.server.start()
	def broadcast():
		viznet.server.send(UPDATE,message='Hello')
	def othersend():
		viznet.server.send(OTHER_EVENT,otherMessage='other event')
	vizact.ontimer(1, broadcast)
	vizact.ontimer(3, othersend)
else:
	viznet.client.connect(SERVER_NAME)
	def onMyEvent(e):
		print 'Received event from server with message:',e.message
	viz.callback(UPDATE, onMyEvent)
	def otherEvent(e):
		print 'Received event from server with message:',e.otherMessage
	viz.callback(OTHER_EVENT, otherEvent)
