you asked about minecart features in craftbook. why not just use Minecart Mania? it has 99% of the functionality of craftbook's minecart stuff plus some more interesting things. if you leave out the craftbookvehicles.jar it will allow minecart mania and craftbook to work seamlessly with each other. this way sk8 can work on something more pressing: Integrated circuits.
