[fab] Metrics: What we *could* get

[Christopher Blizzard]

There's another interesting aspect of having something on the machine 
that allows someone to be counted.  It follows the software all the way 
from where we put it up, through the mirrors and down to the 
installation.  It's much more reliable about reporting something in that 
sense, rather than collecting stats from mirrors and download sites.

It also reports the act - "I'm using it" instead of "I downloaded it."

And last, in some ways it's a lot less nefarious than tracking 
downloads.  It's a result of a positive act on part of the user, as 
opposed to tracking on the backend without any kind of positive assent 
from the user.
