Hi

Technically, I think it is better to write a native driver, because
- the OGR model is not 100% identical with the QGIS one. E.g. one table 
can contain multiple geometry types, OGR has datasource/layer model, ... 
(probably more that I don't recall now). Providing a proper mapping 
between OGR model and QGIS model requires more effort than a native driver
- more direct geometry transfer with native driver, thus better 
performance (with OGR driver, geometry is converted into OGR geometry first)

Regards,
Marco
