Ernie over at LAMS has been working on LAMS "Tool Adaptors". These allow you to use the LMS, e.g. Moodle, .LRN, tools such as Forum, inside of LAMS with far more integration.

The secret to understanding this is to go into the .LRN and Moodle pages and watch the vidoes of the Forums integration.
But the real power and promise isn't in using Forums, its the concept of being able to integrate tools from the LMS in rich ways with LAMS. That opens up a wide world of possiblities for creating customized solutions for learning.
