.fdi files and HAL

Hi all,

I am really intrigued by the concept of .fdi files and how a 
collaborative network of contributors could allow .fdi files to be 
created for a vast range of devices. I am still quite new to HAL, and I 
read through the specification properly tonight, but I have a few 
questions I hope you can answer.

 - Is it preferable to have an .fdi file for *every* device. I know that 
the spec says that many devices can be determined from device 
information, but is an .fdi better for overriding that information and 
providing concrete information on the device?

 - Is the plan to be able to download .fdi files on the fly from the 
net? I saw the Fedora Hardware Project which seems to be a non-starter 
from my initial googling.

 - What is the best method of creating .fdi files? I don't mean how to 
write XML, I mean, how do I find the most detailed information to write 
the key-value pairs for the .fdi files?
