Comment 3 for bug 1544670

I would like to take this idea further. From a developer point of view we should have all possibilities there are to plug-in into the greeter. Hence, as a developer you should be able to provide an application / plugin / addon (you name it) that provides:

- attaching background images, videos, animations to the greeter
- unlocking via a pin code
- unlocking via a gestures (circle, swiping, etc.)
- unlocking via fingerprint scan, iris scan, face recognition, DNA whatever (near-term sci-fi stuff)
- unlocking via remote commands and devices (e.g. via smart watch, near-field communication, etc.)
- placing emergency phone calls (included by default for regulatory reasons, obviously)
- etc.

This way the "circle design" could be totally optional, and it could be easily provided by fans of this idea in the Ubuntu community. It would also lead to a flexible, future-proof, clean design and implementation. Only the basis should be provided by "the platform", Ubuntu Touch.

All this "API stuff" is mostly technical, but UX needs to have their say too. Please, go ahead. I'd be happy to see some movement here. Cheers!
