My code still has to pass the test on the real device, but at least performance on the desktop for map drawing currently is ok and even if rendering quality can be improved I do not expect it do completely fail. The trick is the limit the number of points on the diplay and gradually fading out details on lower resolutions. Lowering the number of visible points will gain performance in case of problems - and might even be OK to reduce details on the limit screen. Possibly IO will be more of a problem (for routing currently it looks like is!). I also do not see a problem with data size. It look like I will get germany below 1GB, which will not be a problem at all on next generation devices (and there are still ways to get data smaller).

Yes I know that there is a GSoC project but this is the first time I see results. At that time it was announced I already started and was more than satisfied with my result ;-) It also looks like aproaches and goals do not exactly match.

See http://libosmscout.sf.net for screensshots and even a small video with first performance impressions.
