@CWatkinsNash - thx for your thoughts. I'm going to throw a monkey wrench in your plans and shortly release a new version of the Reading List plugin that incorporates all the functionality of Book Sync.
I'll let you make any comments on the Reading List thread. It will effectively deprecate this plugin - certainly you would not have both installed and there will be nothing that Book Sync currently does that cannot be done in the Reading List plugin.
I'm like a dog with a bone I'm afraid, I told you it was gnawing at me...
