[Suggestion] Keypad

Keypads are placed on walls similar to Levers and require a 4 digit code to be put into it to open it. The first time you input a code into it the keypad it'll remember that as its code. Whenever that code is input into the keypad in the future, it'll output redstone signal similar to a lever.

The GUI for the keypad would be a typical 10 digit numpad with 4 digits allowed for the code. Clicking any of the numbers puts it in the next available slot.

I was thinking about this while designing my new factory/research lab, there are places I think should be offlimits to other people, would be nice to have doors locked using a Keypad.

Or maybe a keycard system.. Dye colored keycard system..

Do you have any idea, how fucking hard it would be to implement?

I don't

lol

Considering the Redstone Timer from Redpower uses a nice button based interface, I can imagine this wouldn't be too bad.

Not impossible to implement, using tile data to store the number. Although couldn't they just break it, and place a button, or break it and replace it, then reset the code? Also, I wonder if this would be more appropriate for redpower or some other redstone mod, as industrialcraft seems more about machines that use electricity.

I beg to differ, Industrialcraft encompasses a wide array of modern machinery/technologies. I think this would fit much better in IC as opposed to RP.
