Looking at services like http://www.itoworld.com/map/35#fullscreen, it's clear that much of the data is there. What's the best way to go about this? Anyone try it before?

How often do you want to request the data?

1) Build a local DB.
2) request the maxspeed from the highway nearest the stated coordinates.

For extra marks, you might want to build in some logic and some persistence.

Seems pretty straightforward.
