FWIW, finding duplicated code (particularly in a language-independent manner!) is a surprisingly difficult problem. You need to scan not just for large copy-and-pasted blobs, but code chunks that have just had constants changed, variable names adjusted, indentation style changes, etc. I've been working on a tool for this in my spare time, and I hope to have it out sometime this summer.
