But would you be able to tell anything meaningful about the speed that way?

Maybe the easiest thing to do is just define the plugin as not working if
there's a proxy, and automatically disable itself in that case. If your
systems are going through a proxy, you 1) are already modifying the yum
config (right?) and 2) you probably want to set the repo by hand so all
systems are hitting the same one so you can cache efficiently.
