Would plagarism software settle the “Dreams” debate?

As more questions arise regarding Obama’s contribution to his own autobiography, I wondered whether a software program could be written to compare his known writings (which, other than Dreams, are almost non-existent), to Ayers’ prodigious output.  Turns out such software already exists and at least one person claims that it shows that a 16th Century play is a collaboration between William Shakespeare and Thomas Kyd.  I’d love to see that program turned on the possible collaboration between Barack Obama and William Ayers.
