duh, didn't think about suggesting that. however, having a local
socket doesn't make sense if this is supposed to be *distributed* -
use APC (in PHP) or some other local caching mechanism if you don't

thats originally how i was going to do it, except people can wreak
havoc by issuing flush_all and such. depending on how many people use
it, it could wreck the whole point of having the cache there...
