***APP for unlocking the phone using hardware buttons

I know it sounds pretty worthless, but on the hero their are 6 hardware buttons, and if their could be an app that would unlock the phone without having to enter the passcode that would be awesome.
for example the combination of pressing talk twice and menu one would unlock the phone, of course you could create the combination of hardware buttons to unlock the phone.
You would not have to type in the password to unlock it using the hardware button combination to unlock the phone.
So if you were to just press the end key to normally unlock the phone, the phone would wake up and prompt the unlock screen, but if you pressed the combo of hardware buttons you wouldnt have to do that.
