Any other uses of memcached?

[Richard Jones]

Hi
We're using memcache at www.last.fm to pass data between a java 
streaming server and the php website
the streamer puts the name of the song it's playing in memcache with the 
username as part of the key
php reads it on every page load to show you what you are listening to.

We used to have to hit the database to do this, which was rather 
obscene. hitting memcache on every page load is much nicer
:)

wwe also use it for the audioscrobbler.com submission system, because we 
receive a high volume of submissions we use memcache to store 
authentication details and session keys in memory; again this was a 
massive strain on the database before memcache came along.
