Found an almost exact analogy...
http://en.wikipedia.org/wiki/Community_Shared_AgricultureThe way those work here is you buy a "share" in the commodities produced by the farm and each week you get your share of production. The people who buy shares don't own the farm, just it's output.
Find legal basis for those, structure LRM accordingly.
I do like this idea. You're right that there are very strong parallels between the structure of a CSA and the original promise of what LRM was supposed to be. I'm not sure if a good lawyer could stretch the agriculture to mining anology enough to make it work, but this would be a much simpler solution than what I suggested in my previous msg.
