At the moment, the preference system is binary.  It works like this: If
the mirror was reachable during our last test and the mirror has been
updated in the last 48 hours, then the mirror is available for preferred
status, otherwise it isn't.

Certainly it is a possibility.  The issues I see are as follows:

1. Is there a problem here to solve?  ie, are people getting badly
performing mirrors because of the current system?  If so, should we just
remove the poor mirrors rather than use a more complex system?
Unfortunately, I don't see any way to gather statistics to answer this
question.

2. We don't have very good communication with a large chunk of our mirror
sites.  Not everyone is on this mailing list, so it might be difficult to
get data on mirror capacities.

We are always, of course, open to suggestions and further discussion.

Joshua.
