Hi Sander & Emil, Thanks for the quick responses. The usage of the lua script is particularly useful.
I completely respect the limitations of the demo server and can offer to set up another server to support the project. 20Tb of traffic should help? I've been following the discussions on the OSM forum and they've discussed the quality of the map to a great extend. For planning purposes I appreciate that the main source of error is delay in updates. To counter that we are planning to use our commercial help-desk to collect information from drivers about detours and unrecorded obstacles so that OSM can get the updates with less than a days delay. We can also track some vehicles, and capture information such as slowdown caused by traffic jams, etc. on major roads. Hopefully this can become a valued source of information? If somebody has a burning interest in accelerating this, then please feel free to get in touch for a sponsorship. That's the least I can do.
