I have a mobile map application. I have found that directly accessing the tile server works the best. Trying to draw all the map details at runtime on a PDA is a bit much. It can be done, but pre-cooked tile are much better.
The main use I would have for the mobile API would be for place name lookup and a routing network. At the moment neither of those exist in a usable form. On the note of mobile applications. I think it would be useful to create a DB of cellID's. CellID's could be collected from PDA phones with a GPS attached. With the CellId, someone without a GPS could get their approximate location on the map. It is a bit like doing tracks. For each CellId there will be many lan/lon recorded values. It doesn't make much sense to dirty the normal database with these. Instead they would need to be processed and turned into a single point or maybe even an area.

We develop a mobile application (in J2ME) that uses OSM tiles. And while I would support the binary protocol, currently we retrieve resized tiles (because drawing vectors isn't exactly easy). We have done a bit of optimalilsation, but sofar just stick with resized jpegs. Have others been doing things like this?
