(A) Instructions for adding an IMS content repository to Moodle are available from Moodle docs:
http://docs.moodle.org/en/IMS_content_package
This works. The required new folder must be situated in the Root Apache server folder. As such it is not secure. If protecting your intellectual property is an issue, that's not the best option.
(B) If storage space on your webserver is not an issue (unlimited storage space), then it is also possible to deploy IMS or SCORM content within individual Moodle courses by manually uploading IMS or SCORM learning objects into a lesson.
IMS or SCORM content deployed in this way is more secure because it resides in the Moodle Data folder, i.e. outside the server root.
This solution is more secure, A possible negative is content placed within lessons this way is rduplicated with each additional copy of the lesson. This wastes storage space on servers by duplicating the IMS or SCORM content. (IMS and SCORM files can be big.)
If you decide for B above, I recommend exploring use of a DOOR Content Repository. You can find it in the database of Moodle Mods. The latest version is available on Sourceforge.
http://sourceforge.net/projects/door/
The new version of DOOR (1.8.x) supports exporting Moodle content and importing both IMS & SCORM LO's directly into Moodle lessons.
Installing DOOR can be tricky.

Don't hesitate to contact Mauro Nidola, who is one of DOOR's primary developers. He's a great guy and resonds to requests for assistance. (Posted earlier on this thread.)
