If you haven't done it then I'm going to suggest that you also work on mobile apps to make phones be as loud and annoying as possible. Yeah, it sounds stupid. But a random Blackberry can be as loud as a Skytel pager, even if it isn't by default. And it is worthwhile for someone on duty to make it so.
you know what I want? I want some sort of arm band to put my cellphone (or, better, a giant bluetooth vibrator) so that when I sleep, I can be woken by my pager without waking other people who may also be in the bed.
