Richard, we are VERY interested.
How is your project going? (we are a group of lecturers from several universities, and secondary schools that have been using Tiki for educational scenarios and educational centers' sites, and we recently got some more funding to keep on our work...). And we are VERY interested in integration of TikiWiki and Moodle, or Portal based upon tiki code, and LMS features from moodle (at least, the ability to use moodle modules).
See more about us through: http://tikiwiki.org/UniWiki or http://uniwiki.ourproject.org
