[gdal-dev] OGR XYZ -> GDAL VRT?

[Brent Fraser]

Hmmm.  You need the GDAL-VRT format to have the same data-source 
flexibility currently in the OGR-VRT. Could be a useful enhancement with 
the growing interest in storing rasters in a RDBMs...

I can do it programatically but want to do it on the fly, so MapServer, QGIS, etc. can simply use it.
