Actually the idea was that "catalogs" would really be query engines that 
used free-floating indexes configured for them.  A typical sort of query 
engine would also be an event subscribable, filtering events from the 
event service, only emitting those having to do with objects for which 
the query engine was responsible.  Member indexes would subscribe to 
this query engine for their events.  Again, this would be typical, but 
other configurations and query configurations would be possible..

I don't think Jim nor the new catalog (not having looked at it yet :-) 
share that approach, though, and you actually have a catalog (as opposed 
to those of us who planned to have a catalog), so I won't personally 
wave my hands about too much.  If you don't *need* to remove the 
stand-alone nature of the indexes, then why bother?   But that's all 
I'll have to say.  :-)
