[gdal-dev] Can GDAL Access Raster File Stored as Blob in SQLite3 Database?

After evaluating the Rasterlite driver and database, I've found it to be
able to support everything I need except store projections for multiple
rasters. I've seen hints of a Rasterlite2 driver in the works, but as of
yet it's not available. I would prefer to stick with sqlite3 rather than a
more complex solution using PostGIS or another server database. The
rasters I'm working with are sized a few megabytes and order in the hundred
of thousands to millions. In the meantime, I've stored each raster file
(tiff format) as a blob in a table, which can be efficiently queried and
accessed. Now to my question: is there a way to pass the sqlite3 handle
to GDAL to read a given band and block from the data? Also, if there is an
easier solution, please tell me.
I'm using a recent build of GDAL C# bindings on Windows 7.
