Well I guess it had to happen. Or, at least, to be proposed. This page is the development wiki for Sloodle - 'Second Life With Moodle'. "Imagine a Moodle course that, if you wanted, could turn into a proper 3D interactive classroom with all your Moodle resources available to your students in the virtual world." This is very doable, since you can import external objects (such as videos) into Second Life. To me, the greater challenge will be fusing an open source LMS into a commercial 3D environment. But hey, it might work! Then Blackboard will say it invented it.
