[gdal-dev] Mosaic question...

I love the gdalbuildvrt -> gdal_translate trick for large mosaicks, but I
have a somewhat more complicated problem I was hoping I could get some help
on. Given a large set of overlapping images, I want to mosaic using the
following "rules": 1) all overlapping pixels should be averaged together,
and 2) any "nodata" pixels in a given input image should be ignored in that
Is this doable in GDAL? Or am I stuck with just the "top" image in the vrt
being the value the output mosaic uses?
