Transactions with rollbacks on Redis Cluster

Hello everyone, I'm the author of Redis in Action, as well as a few other things, and I've recently hit some milestones on my own fork of Redis that provides distributed transactions with rollbacks in Redis Cluster. Any key, any (master) shard, any operation, as long as the cluster is consistent.

I've got a 2.5 minute video with a quick demo showing it in action, at least for a couple simple operations. Please let me know what you think.

Thank you, https://www.youtube.com/watch?v=2mN4UWogHJA
