Using memcached w/ socache

Before I start digging into the code to try to figure this
out, has anyone use the memcache socache module to use
memcached as the backend storage for mod_cache? I'm trying
to figure out exactly *how* to configure this...

I'm guessing it's something like

CacheEnable socache

but who knows.... IIRC, using shmcb is like:

CacheEnable socache
CacheSocache shmcb:/var/tmp/foo.shm(512000)

so I'm figuring by analogy thats how memcache is.
