Anyone wanting to learn more about information theory, decrypting to multiple plaintext messages or unbreakable encryption would find it interesting. OTP is an edge case and it does not scale (I understand that), but is useful for small messages between two parties when privacy is paramount. Government states have used it.

Also, I can't find any other OTP source code that compiles and works.

You take a file an xor it with the pad. It's like five minutes work, tops. The user interface on top of that might be very interesting, but I honestly find it hard to imagine that the underlying algorithm could be messed up and that you'd still have something that could use the keyfile on something encoded to produce a readable plaintext.

Not wishing to be a drag here, but it's been done over and over again in every intro to cryptography class I've seen.

Sorry ^^;

Sure, learning is good. Any introductory crypto class would consider OTP for a bit. But you seem to be asking people to critique the system as if it would be used for a non-educational purpose. (If that's not what you mean I apologize for misunderstanding.) That just seems really unlikely.
