If you want, I can work on a table how to process each of the listed
datasets. Some have odd issues which should be resolved before
publishing them (e.g. "natual Earth" is larger than the common earth
definition etc which makes some GIS unhappy). I have recently filled
holes in SRTM using spline based DEM reconstruction and so forth
(needs much computational power). On DVD, I have all SRTM Version 2,
but no space/computational power to elaborate them :-)

Let's see what Norman tells us. I am ready to start and would need
parts of the OSGeo software stack been installed or the possibility
to install it myself (preferred). Then we can

- fix odd data and formats
- start to extract areas of interest
- derive new maps from existing ones (e.g. make a hydrological sound
  DEM from SRTM3-V2 which globally doesn't exist yet)
- split result maps into chunks for WMS/WFS or whatever is appropriate
- identify regions of interest for Edu datasets with enriched data (also
  social data etc).

Best
