Edit: I've downloaded Calibre and created a lrf file, but I want it to be checked by a Sony owner before I upload it. UncleDuke, as you asked for it, I've sent you a PM.
PS Edit: Well, look at that! Calibre has a built-in Sony PRS emulator. The book looks OK to me, but the ToC is only at the end. I guess that's alright, but I'll see what UncleDuke says...
