Sync Entourage Tasks

Does anyone know if it is possible to use AppleScript to sync Entourage tasks between multiple computers. I am an AppleScript developer but I specialize in graphics software scripting and have never scripted Entourage. I have a client who needs to sync Entourage tasks between several machines. He says Entourage does this automatically every 5 minutes but wants to be able to manually trigger the event with an AppleScript.

Is this possible? If so, how much would you charge to write such a script?
