Stephen,

GDAL has some basic mosaicing functions now.  In the sense that gdalwarp can
be used to successivly overlay component images into a mosaic.  This includes
control of "nodata" values for each pass.  However, it doesn't include
cutline support or feathering across cutlines which would be quite desirable.
This is definately a direction I would like to go with GDAL.

Best regards,
