How to get started with developing accessories for iOS?

Question

We want to develop iOS accessories which plug into the 30-pin dock connector. Is there a good starting point for beginners which talks about what can and what can't be done with the EAAccessory framework?

Apress has released a book in June 2010 talking about the EAAccessory framework. Is this still relevant, or has Apple intrudoced lots of new APIs since then? Are there other resources available?

I just came across a program on the Apple Developer site that might interest you: https://developer.apple.com/programs/mfi/ Might be worth checking out as a starting point.
