Hi Derek, We're just starting that process now.
Currently we have three short tuition activities uploaded to our development Moodle that were created in Articulate presenter and seem to have integrated seamlessly. The only issue so far has been that an embedded SWF in the splash slide failed to play in Moodle, but other than that the modules are fully functional and the SCORM integration seems to be working well. None of the presentations include quizzes though...
We followed the process outlined in Dave's excellent tutorial at MoodleTuts to upload the Articulate content and had no problems getting it to work.
You can see the examples in out free course section at http://inxtraining.kt-intl.com.au
HTH,
Pete
