Customizing Android Lock Screen functionality?

I will like to develop an App which modifies LockScreen 开发者_高级运维of Android. I have read in some forums that it is not supported as yet in the SDK but there are some applications available that does exactly that.

One can surf Screen Suite Lock Screen

Can someone let me know is it actually possible to customize LockScreen and implement our own way of Lock Screen?

It is possible to have views displayed above the lock screen and to make it dismiss the lock screen. It's a dirty solution, but the only one as long as there is no api to replace the lock screen.
