I don't think it's not that anyone's not interested, just that this section of the forums seems to move a little slow. Anyway, I've heard of this hack before, but never actually tried it. I've read on Apple's Discussions site that this could technically invalidate your warranty due to the fact that it changes your firmware (although it's reversible), so you might be careful with it. It's a nice hack, though. It makes me wonder why Apple doesn't just give in and make dual monitor support standard on iBooks.
