Did read the Article, congratulations.
I agree with some spokesman in the article that it is to early to stick to the moving target: universal standards. The point is that a product like Moodle develops new views (like the selfreflection of students) that are not covered by standards like SCORM.
On the moment I would prefer in Moodle a kind of:
"IMS contentPackaging waiting room",
where you can view the structure of the IMS/CP Outline in the Manifest, but the can map - yes, by hand - the resources against fucionality in Moodle. Automatic Mapping is a illusion: Not all cars will be black.
(Starting with database-structures and moving to XML is a good survival strategie?)
By the way, how many Martins are there working on the system in this "robust development and user community.."??
Fle3 is a nice option to have as a module inside Moodle, so is D3E, not mentioned in the Article but a nice product from Britisch Open University: It's the combination of a source on the left and a discussiontree on the right.
Some of my D3E-mockup-imitations, top be recreated in Moodle:

https://elo1.hetstedelijk.org/martin/dubbelhotpatatoes1.html (= read the text and answer the questions, idea from hotpotatoes)
https://elo1.hetstedelijk.org/board/toep4.html (a movie, but worth the waiting: question for the discussion in a multimediaclass: is this real or manipulated, please discuss..)
https://elo1.hetstedelijk.org/board/toep3.html (a 3D object for discussion, and so on)
