        Don't join, perhaps? We already have the (protocol)
        machinery to do this. It seems that the problem is
        with the users (they join groups that use their 
        commodity link). How does this happen? I have two
        (or more paths) to the same source, one commodity and
        one I2? And what, I don't prefer the routes from
        I2? Then I don't prefer I2 (or am misconfigured). 
        Or is it something else?
