Using memcached

If you're not familiar with memcache(d), it's a wonderful and seemingly obvious way to manage data across distributed systems. Go's built-in channels and goroutines are fantastic to manage communication and data integrity within a single machine's processes, but neither are built for distributed systems out of the box.

This is useful for caching data for systems with high turnover such as web applications, but it's also a great way to easily share data across multiple servers and/or to utilize shared locking mechanisms.
