Study sounds like a good idea. You might find that most of the outgoing
queries are for stuff that either has ultra low TTLs ( major websites etc )
or which is only queried once ( Spambot, RBLs ).

As for a solution I'd tend to lean towards memcached , It's distributed,
fast, popular and supported by the language of most people's choice.
