Redstone Processor with Scripting Language

Imagine being able to let people in to a secret base if you allowed their username or not. Or being able to determine what's what in a chest. Or doing both and everything like that. Hooking up a redstone processor to a chest or possibly a redstone camera (which doesn't exist) to create elaborate computing systems. The redstone processor's crafting would be three copper ingots at  the top, dust, redstone torch, dust in the middle, and all copper at the bottom.
