It would be great if we could have a whole eco-system of "filters" that
would receive some types of announcements and would generate new ones.
This could even be efficient if there is some way to check if there is
anybody subscribed to a given event (then the filters generating these
announcements could suspend their activity, unsubscribing from their own
inputs in turn, until someone interested showed up).

Some application might just want to get text independently of whether it
was typed on the keyboard, recognized from speech or drawn with a pen. A
game might want to see raw keyboard events to deal with keyDown and
keyUp separately, though it would be better for there to be a "game
filter" that handled this so the application could use they keyboard,
multi-touch gestures or a fancy joystick equally well.

About the general idea, I agree that the interface between the VM and
the image should be changed as little as possible (not at all would be
ideal, but it unlikely with iPhone and such) and that the current
in-image APIs should remain available for full compatibility - only new
applications would take full advantage of the announcements.
