puremvc is a good alternative, and has pyjs examples (timesheet and employeeadmin that I've looked at, and examples/misc/gaedjangononrelpuremvcblog looks interesting, too!) Puremvc has wonky nomenclature, but it does the job well. It's a sort of event-oriented superstructure you overlay above the pyjs components. You can look up your data holders and component managers by name. You can send notifications out, and you can register listeners to react in turn. When your app is properly configured, the app's components do not know that data and user interactions are managed by puremvc, so components with the same api can be switched out at will. It's worth a look. http://puremvc.org If you find your brain turning to jello with the puremvc jargon, the puremvc examples can at least provide a template for experimenting with PyDispatcher. - Jim Washington
