The nature of our traffic means stickiness doesn't work so well for us.

We basically proxy for lots of large corporates.  They often have the
same IP from our point of view for lots of their users.  So we can't
easily balance that traffic on the way in based on IP.  It's possible we
could balance on something else but I'm sure some of our dear customers
would confound our plans.

I'm still pondering this one.
