It's not really suitable for vector data, though. Firstly, the concept of
zoom levels doesn't apply - the vector data is the same at every zoom. You
could choose an arbitrary zoom level, perhaps, but you then risk choosing
one that's either too small-scale for mid-Wales (hundreds of empty tiles) or
too large-scale for Karlsruhe (a few very big tiles). Secondly, to rephrase
Jukka's point, "everyone" is only "every OSM nerd", not "everyone who wants
a simple drop-in map for their webpage".

Nic's suggestion looks interesting and I wonder whether
xmin_ymin_xmax_ymax.osm, with a configurable option to use either integer
projected co-ordinates or raw lat/longs, might be a good way forward.

cheers
Richard
