As part of an experiment with WebGL (3D in browser rendering of OSM data) I'm planning on doing, I've developed a quick read-only OSM API and data format optimised for rendering. The rationale was, that if the front end is doing only rendering of OSM data (no editing), the standard OSM XML format is not really optimised for this purpose. A better data format for rendering would contain only point of interest nodes, with ways represented as polylines of points, with no need for the client to look up the coordinates of the way's constituent nodes by ID.
This API generates either XML or JSON describing points of interest and ways (as polylines) in a given bounding box. You can find more details on the blog post: http://www.free-map.org.uk/wordpress/?p=21 It's fairly quickly put together so might not handle errors gracefully just yet.
