Good to know that everything around .LRN is moving fordward.
Galileo has provided the IMS Enterprise v.1.1 specification that allows you integrate automatically your legacy systems (i.e. student - courses database) with .LRN.
FYI, Galileo has launched a pilot .LRN (2.1) instance a couple of weeks ago [ges2.galileo.edu]. Running like 12 courses with more than a 100 real users, so far has been a good experience with good feedback from the users. Our plan is to fully migrate our system to .LRN (2.1) in 2 weeks from now.
