well, as far as ruby/erb is concerned there is no ESI, right? it
simply produces:

<esi:vars>

State: $(GEO{'region_code'})
City: $(GEO{'city'})

Massaged city:
whatever-the-value-of-CITIES["$(GEO{'region_code'})"]["$(GEO{'city'})"]-is

</esi:vars>

the hash lookup occurs before ESI gets any chance to replace the
variables. so i don't think there's any way to achieve what you want
(other than going back to the server by some means after ESI
processing has happened). i'm totally unfamiliar with ESI, though,
so i might be off.
