With the release of Moodle 2.0 DH is faced with a rather thorny problem, in that DH will support only version of Moodle at a time.
IMHO M2 is not production software and a review of the postings to the Moodle.org fora amply demonstrates the myriad issues that anyone thinking of using Moodle 2 must face. I am afraid that I have to argue that DH should stay at Moodle 1.9.x until such time as Moodle 2 is fully functional and stable.
What do you think??
