I would love to have the map data available in a more usable format... some database format that can be moved and translated to other database formats would be great... for instance MySQL for web applications. With the correct data it would be totally possible to create a flash based mapping software or other. It would open up a lot of possibilities! I tried a long time ago to look through and try to decipher the tiger map data. Its just a very confusing format. If a script can be written to convert/import it into a database that would be great!
