Have you ever tried to call ICommand.CanExecute()? It actually works fine, but only if you are not as naive as I am... Simply calling it without the proper know-how might result in a NullReferenceException, so what you should read is how to implement ICommandSource. See

1 - UIElement.Opacity and the way it is being 'inherited'
