I don't see any particular downsides there that aren't just OGR's support
(ie. no spatialite+indexing)... ? The 'no datatypes' thing doesn't apply in
the same way to SQLite v3 as it did to v2 (more at
http://www.sqlite.org/datatype3.html).
I'm not suggesting it as a replacement for PostGIS, but as a replacement for
Shapefiles - portable, single file, compact, efficient, relational, "just
works", etc. While someone non-technical might fire up QGIS and open a
spatialite db, its a completely different thing to get postgis running and a
dataset loaded, and thats before getting QGIS to connect to it. If you're
using large datasets then a DB server solution will be necessary - you'll
have the same problems today trying to run everything off Shapefiles - but
that level is simply not required for many people and problem classes. And
SQLite should kick Shapefiles in nearly every metric by a significant
amount.
As you said, getting it into OGR is the first step - but it'd be great for
the desktop apps to pick up and run with it as well, not just as another
import/export option.
