Assuming you do have a network connection, like the example above; What 
would you want to do if there's no Jigdo, but you do have the Fedora 9 
DVD, and you want/need the CD version too? Download another ~4GB of ISO 

How about off-line?

It's fairly simple to create the Jigdo files and host them. Let's try it 
and get the real numbers, then decide if it's valuable enough for all of 
us to continue distributing installation media with.

We on the other hand have hundreds -if not thousands- of users download 
the CD version of Fedora 7 and Fedora 8 while supposedly they are in 
possession of the DVD images already.

Kind regards,
