I think the ISO install from CD would be a brilliant idea.
All that need to happen, is for the compressed / uncompressed image to be on the cd, and a feature like with PCLinix that will allow you to run a command to install to the hard drive.
If we can get the commands together, then fulvio can add the command to the web interface.
You can delete all the partitions from the web interface, and then run the simple DD command.
How difficult can this be?
