For the Cordova specific quickstart there should be instructions for JBDS import & execution.
For the Objective-C quickstart, I assume there is nothing "odd" about it, so an Xcode savvy individual should know what to do with the project
For the Android Java quickstart, if there are some oddities about how to import it into Eclipse then those should be described, otherwise I assume most Android Java savvy individuals know what to do with the project.
