The IMS Cartridge is a newly introduced mod, essentially a common capsule of course materials that can be zipped and unzipped. AFAIK, the only activities that can be exported to IMS Cartridge are Forums, page resources, some quizzes, labels and URL resources. There may be other things by now, but if you are trying to include some other activities, then it may not happen. As it is still in its infancy, I would be a little reluctant to use it as anything other than a testing tool.
