thanks for all the replies.
that ThrottleLock looks promising.
is there a way to modify S2U2? i really do enjoy that app and i use an animated Gif as my lock screen wallpaper... i don't think you can do that on ThrottleLock. is there a way to just remove the slider and "slide to unlock" from S2U2 so that you unlock the same way but you couldn't see the slider?
