I feel like this provides support for the Amazon sync feature while still allowing a value to be input (UUID) without user intervention.
This feature only works if an ASIN has been set on the ebook.
I think it is great that you are exploring the possibilities and expressing them in actual code for review. I am not a programmer but any book converted to mobi with the current version of calibre should already work with the Amazon Sync feature.
What difficulties did you experience trying to sync?
