This thread is (kind of) old but I thought I'd bring it up...
I thought it was really cool you guys were doing that. It's so funny; I'm actually in the midst of writing (and rewriting and rewriting and rewriting and rewriting) a book of fiction, where I'm writing the same plot from about ten different peoples' perspectives. (Which is, by the way, excrutiatingly difficult for me. All of my characters keep ending up sounding like the same person.)
Anyways, I just wanted to say congratulations on it, and good luck, and to share this. I was re-reading through the threads and thought it was such a coincidence!
