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.
