  are*already*sold today. Such data, even if of strategic importance as is the case with digital 
  
  cartography, are only a minimal fraction of all the PSI that could and should be opened to increase 
  
  transparency, reduce the costs of Government and stimulate the economy. In all these other cases: 
  
  •  the money to generate the data already arrives by some other source than sales and 
  
  licensing(but even with those data it may be possible to generate them by crowdsourcing, 
  
  thereby reducing those costs!) 
  
  •  the only extra expense caused by publishing those data online (assuming they're already 
  
  available in some digital format, of course!), would be the hosting and bandwidth costs, that 
  
  may be greatly reduced by mirroring and other technical solutions like torrents, already 
  
  widely used to distribute Free/Open Source Software (FOSS) through the Internet.
