uses for memcache

Been using memcache to cache conf files for a little bit now, and am pretty
well thinking it rules. It just works. Anyway, I have been pondering other
uses for memcache and have come up with at least two, which others are
likely already doing, but here you go
1. System/network wide locking. Try and add a key based on your
host/process name, perhaps with a ttl. When you finish with your process,
delete the key. If the process dies, the ttl kicks in.
2. Service checks. Guessing memcache is about as fast as snmp, and I
think easier to implement. So your monitor box tries to add a key to
memcache named something like ping.$time, with ttl of a minute. Be a pretty
nice heart beat.
Just wondering in what other ways people are using memcache beyond perhaps a
simple database cache or the like.
