A couple of days back, I converted the SRTM dataset into tiles containing OSM contour lines. Meanwhile the tiles are available online. This service is provided by the Stuttgart University of applied Sciences, thanks to the support of Dr. Franz-Josef Behr.
I hope the data is useful for some community work, e.g. tile rendering for slippy maps or rendering contour lines into viewports of mobile devices. If you create publicy available stuff from the data, please drop me a line.
