This would be a great APP name. Maybe you can try selling it to iPhone/Android application devs?
$100-$150 in my opinion
Could be.......
1) Spy software but guess it wouldn't have value,
2) Some software for deaf people
3) Password Protected Secure PDF service
4) A tablet that has auto rising dots for braille, to help blind people
I'm sure there could be more uses these are what came to my head
