Carson,
This is great. This is exactly what I was looking for. I'm also
looking at your other plugins and will probably try out several of these
as well. Thanks!
For rasters, using GDAL works great; even projecting in batch mode can
be done with simple scripting. However, including raster srs management
within QGIS will be very helpful for the majority of users.
