Drkae Thank you!!! Indeed I also think it could be done, but I searched the Web and found no previous experience of the like, so maybe it's just too weird putting a spatial-enabled RDBMS on-board buses...!?! Anyway I found the TurnKey PostgreSQL appliance. It's a small Ubuntu-based live-cd with PostgreSQL and PostGIS preconfigured. I could suggest these people to try it out on hardware similar to what they intend to use, to have a feel of how it behaves. Bye Paolo
