One of the changes that is currently being made (as part of v2.0) is to store the data in a local SQLite database instead of the current binary format. I don’t know what language you will be using, but if there is a way to read from SQLite then you should be able to pull the data out of the database and do what you want with it. If you want to share what you have done at that point, I would happily publicize that on the Klok site.
