Isn't MODIS already supported via GDAL?

The processed level 3stuff comes in HDF(4) format, which GDAL
knows, see http://grass.osgeo.org/wiki/MODIS

as for the "raw" level 1B and level 2 stuff which may come by
scan line(?) I seem to recall that was a motivation for adding/
extending the thin plate spine functionality in gdalwarp? but
nicer ways of dealing + processing that could be the intention
of the module..? anyone using that low level data? Markus?

wiki page:
"The USGS/NASA's MODIS Reprojection Tool (MRT) support reprojection for Level 3 data or MODIS Swath Reprojection Tool for Level 1B or 2 data and can be used to create a GeoTiff."

Years ago, we (former CEA, now FEM) sponsored the implementation
of thin plate spine functionality in gdalwarp to georectify AVHRR
data.
The last years, I used moreover higher level MODIS data.
