Paolo,

there is a brillant postgres extension called "pgdijkstra" from 
camp2camp. You need postgres 8.0. It delivers an algorythm for 
calculating the shortest path - you also may alter this by other 
attributes, because you are in the database.

It's a horror to get the first data into the db (I can help) - if once 
done it is quite easy and afterwards it's easy to handle.
