[wp-hackers] Memcached backend for the Object Cache

Public-available servers won't really help -- you're not going over the open 
internet to memcache...

Yes, this seems like only truly useful to:

- dedicated-hosting-box hosted sites
- larger WP rollouts (Wordpress.com, WPMU, smart hosts...) who want to trade 
off physical memory to reduce database and hard disk hits.

Don't get me wrong.. I think it's a cool addition, and a few of the big WP 
sites will find it immensely useful at reducing loads, but for the other 95% 
of folks this is just something to dream about. ;)

The problem is getting >shared< hosts to learn and adopt technical 
approaches that would reduce the load across their server farms. :) 
Reducing disk load (well, and cpu) is a good piece... especially as it 
reduces SQL hits as well.  Can we get DreamHost to try it? ;)

Interesting but potentially useless to most bloggers who don't have access 
to other servers... unless can be used or if there will be 
publically available servers for such purposes.

Yes.  It caches to/from one or more memcached servers rather than using
the filesystem directly.  You can define your servers and ports by
setting $memcached_servers in wp-config.php.  By default, it looks for a
server on port 11211 on the local host.

Example server config:

$memcached_servers = array(' ', '');
