More data source support
Restricting to only PostGIS greatly reduces the usability of TinyOWS. Please consider at least implementing OGR. Best would be achieving the status of MapServer.
+1 OGR :-)
I would prefer tinyows as simple as it is. PostGIS support seems perfect for WFS-T and other cooperate editing services. WFS-T against a shapefile or via a personal geodatabase ?
Keep It Simple and Stupid (K.I.S.S) :-)
A simple solution could be to have a backend for Spatialite, which itself supports OGR external data sources, and is at least a transactional backend.
In any case, this would mean to have support for multi type sources, which is not trivial. Feel free to fund or propose code :-)
