Right off the top of my head, on the "it would be useful" section: - OSM - to - WFS-T bridge (or read-only live WFS interface) - Support for more map projections in JOSM - Support for georeferenced raster images in JOSM (jpg would do; jpeg2000 and ecw would be a plus) - Support for OSM API 0.6 in "traditional" GIS software (arcgis, qgis, grass, gvsig, whatever) - A method for getting submetric GPX traces based on raw data from garmin receivers (build on top of the GPS post-processing stuff at http://artico.lma.fi.upm.es/numerico/miembros/antonio/async/ ) - Tool to automatically detect large sections of overlapping area ways (i.e. administrative borders shared between administrative areas), and convert the area ways into relations (heavy graph theory here) Also, on the "good to know" section: - PostGIS vs. MySQL spatial vs. Oracle Spatial vs. MS SQL server benchmarks. SQLite anyone? - R-tree vs. quadtiles benchmarks. Also, on the "less useful but awesome anyway because OSM has so much cool data" section: - Render the OSM dataset in a cool and useful projection, such as sinusoidal or an Icosahedral Pseudoglobe (that last one would be a nice swag item for the State of the Map). - Benchmark a quadtile solution vs. a more general geodetic grid tree solution (get the quadtile idea, apply it to triangles instead of squares, put 'em on a geodesic sphere; basically, instead if dividing a square into four squares, you increase the chord factor of a fractal geodesic sphere by one). Throw in a R-tree benchmark for good measure.
