This idea has been kicked around for a long time, in fact I did some
preliminary work on it a couple of years ago to help identify the
issues/challenges in such an implementation.
I'm pretty much aligned with Frank's goals (quoted above). I see it as
more than a "shapefile" replacement. It can be a container for
multiple layers with SQL functionality. This allows you to not only
package up everything for a project (web or desktop) but also have the
power and flexibility of an RDBMS.
