Movable Life

I've seen some discussions about Movable Life on the different listservs I subscribe to. Reactions seem to be varied, from saying it has no use to saying it can be useful to monitor activity/students in second life and pop in when there is activity that needs attention. Has anyone started to use this application in their classes?

Here is the URL for Movable Life, in case you are curious:

The concept seems to have promise. If it is useful, perhaps this would be a good topic to submit for the Call For Papers.
