Hi, yes it is Grouper 1.6.

Yes, that's exactly what I want.

I was hoping there was a way to use a hook for flattened membership 
changes, because I'm trying to get a lightweight solution in place 
quickly, and hooks are otherwise working well for that.  In this 
particular case, our structure of course groups, the relationships 
between the groups can be managed by logic in the code, so I'll do that 
for now.  However I think we will have to look at the other solutions in 
the future.
