Lazyweb: literary forensics

[lovingboth]

Are there any websites / Linux programs for helping determine if the same person wrote two different sets of message board posts?

I can find plagiarism checkers, but these tend to be looking for whether the texts have a common source, rather than a common author. (If I write two texts, one about soft fruit and one about deckchairs, they are liable to pass a plagiarism test, but should still have enough in common for someone to be able to say that the same person wrote both...)

Oh, and it's also worth noting that it's even harder to detect impersonation - e.g. determining whether a text is really Dickens or a skilled writer pretending to be Dickens.
