http://3.rdrail.net/blog/memcached-based-message-queues/ Blog pots shows and explains how to implement simple queue system on top of memcached
http://highscalability.com/blog/2009/10/26/facebooks-memcached-multiget-hole-more-machines-more-capacit.html also see http://dormando.livejournal.com/521163.html Describing some problems with performance/scalability you may have if you partition/shard your data by hash. ( that’s what memcached does.) You may hit the cpu bound limit from the amount of requests that few very popular keys receive. Currently, there is now common way around this (perhaps because very very few sites scale to the point when this becomes an issue )

http://www.mysqlperformanceblog.com/2006/08/09/cache-performance-comparison/ gives you an idea how different caching methods perform. Read it before implementing something
