Arguably, most systems are distributed systems today. Even if you're just connecting a Rails app with a MySQL DB. If we had a fabric (which is called Mesos ;) which allowed you to write elastic, distributed systems without the need for worrying about interconnecting hosts and segmenting hosts into static partitions, etc. wouldn't that be a big win? Spark is also a great example for an app that was built directly on top of Mesos - the authors could focus on implementing the actual logic rather than worrying about interconnection. Same is true by the way for systems like Chronos and Marathon - all of which run on top of Mesos.
