As a fallback, you can of course probe addresses on a binary search, 
or even just select a random mirror in the first place.  (If you 
overshoot the list, you just decrease the max on your binary lookup.)

Non-random selection is tougher to implement, since you'd need to 
keep some kind of history to make it work effectively.  Determining 
the length of the list is a trivial problem by comparison.
