Now that really _does_ have promise for slimming down SRTM filesizes.

My workflow for SRTM is GeoTIFF->DEM2TOPO->Polish format->Perl  
script->Illustrator->simplify to beziers... which produces nice  
manageable files. Clearly those particular tools wouldn't be much use  
for OSM, but the principle remains.
