see, specifically ISC-TN-2003-1.  (as a bonus, this
TN was markuped using the recently mentioned tools from

f-root works this way.  paly/sanfran, san jose, madrid, hong kong, and new
york city are all bgp-anycasted.  (with plans for several dozen more cities.)

as long as you don't make silly assumptions about client locality based on
"which anycasted server heard it", such that you give back incoherent answers
in hopes that they will be somehow client-optimal, bgp-anycast isn't even
controversial at this point in time.
