There is certainly going to be a lot of interest.

Questions:

* Can it serve as an interface to multiple database backends?

* Is there a portable, freely available database backend?

* What are the restrictions on the value types which can be put in
containers?  Certain specified types only?  POD's?  Pointers?

* What is the abstraction cost?  For example, since the STL container 
interface doesn't distinguish read access from write access, are you forced 
to re-write every element touched by an iterator, resulting in a huge 
penalty compared to a native database implementation?

* How are issues of multi-user update locking handled?

* How are commit/rollback issues handled where multiple database 
interactions have to be viewed as a whole to complete a transaction?

* In general, what are the limitations?

I guess what I'm trying to understand is the extent to which your library 
is robust enough to be used in production applications with all the 
attending messiness.

Thanks,
