What I was thinking about for some time for experimenting on www.openstreetmap.pl was that the subset of data would be loaded together with the bitmap tiles in a txt or json file and objects such as big roads or buildings highlight when you mouse over them, perhaps after a short delay. Particularly I wanted this in order to display somewhere the link to the wikipedia page linked by the means of the wikipedia= tag that is getting more popular these days, at the same time the object's shape highlights on the map. My idea for implementing this would be that the txt/json files would be generated by the renderer at the same time the tiles are generated and in a similar directory structure of z/x/y.txt tiles, with the amount of objects conforming to zoom level. A single txt tile would perhaps cover nine or sixteen bitmap tiles area as to not generate so many http requests, and hopefully the browser would cache them like the bitmaps. Note that I don't know how doable this is yet, but I think it would serve the purpose of "showing off the data" well.
