One project I had in mind was osm->shapefile direct. Whether I do this depends
on time factors however, at the moment I've got the following things I want
- display landsat on JOSM, for area drawing
- build Freemap
- work starts again on October 1st :-)

Given the issues with Chris' renderer, would it be worthwhile me doing some
work on the current renderer, to improve/optimise it? If you (Steve) or other
people think so, I'll prioritise time on that, because obviously the renderer
is a big part of osm.
Might rails mean many of the performance issues with it lessen anyhow?
