Forum .LRN Q&A: IMS LD and coppercore integration?

"The OUNL has not released CopperCore as just a boost to the IMS Learning Design specification that it helped design. It is already used and operational in a pilot of the Alfanet environment, where it is integrated with other tools. One of these is .LRN: an enterprise class course management and collaboration framework from MIT Sloan and Universität Heidelberg. This is built on OpenACS, which is built on, arguably, the most powerful webserver there is: AOLserver. Clearly, Alfanet is building the whole stack to handle lots and lots of concurrent hits. According to Hubert Vogtens, the OUNL is also evaluating other systems for use in its own learning networks environment."

Is anyone aware of any more details about this?
