I cannot remember who it is at the moment, but there is an individual
that I am fairly certain is subscribed to this list that has a project
that has the functionality that you are looking for. They had put

There were somehow "pushing" the content to the screen continuously I
My memory is vague about both the project and it's author. Hopefully,
