Bill :I'm curious what you'd like to see documented in a book. I'm almost done and starting to think about the next one :)

Hi Bill,
I think there is not a lot of information about lots of Apple's Frameworks such as the PubSub and Calendar store frameworks (ones Im currently playing with), I often find the only source of information is Apple's own documentation. The frameworks them selves are not very large, but its still its nice to have a guide.
