Let's remember to distinguish between the soft real time characteristics of mnesia, and the non-real time characteristics of
'competing' dbms.  

One approach is to interface erlang with a 'competing' dbms to leverage the benefits of mnesia for the data requiring soft-real
time, with the benefits of a non-real time sql database.

In the practical application, you'll almost certainly want your terabyte database on machine(s) seperate from your erlang
application.

Thanks to all for great discussion.
