   I'm interested in this discussion but generally keep my mouth shut on 
the boost list since I'm still very much a newbie to boost stuff.  I 
know that in the past I've needed a map with two indexes into it.  I 
recognize the potential of your multi-index set for both my past 
application and also possibly for creating an SQL (or similar) interface.
   From your descriptions in e-mail, I like the concept.  I have not 
reveiewed the code in any form.  I think that the data structure kind of 
blurs the distinction between sets and maps.  Effectively, access by any 
given index is like either a map or multimap based on if the index 
points to unique entries or not.  I think requiring that all index's 
point to unique entries will probably be problematic.  I don't believe 
that is the case though...  I would also be interested in ensuring that 
operations on a single index are efficient and don't result in massive 
overhead due to the presence of the other indecies.
