[gdal-dev] gradient alpha transparency bands for edge-blending in

I'm using some images with blurred edges (like http://tinyurl.com/6r2s3z4)
to mosaic a larger geotiff with gdal_merge, but it doesn't respect
transparency that's not either 0 or 1. Is there any way to achieve this
without coding my own merge tool?
This is what results: http://tinyurl.com/7xckw98
The command i'm using (gdal 1.7.3 on ubuntu 11.10) is:
gdal_merge.py -n 0 -o warren-township-geo.tif 47539-geo.tif 47543-geo.tif
More detail on this issue is here:
I'd appreciate any tips, and I am wondering if I can contribute if this
functionality does not exist already.
