Hi! While I was at the most recent Offline Camp, I gave a quick 5 minute talk on scalable CouchDB replication and change listening with Spiegel <https://medium.com/offline-camp/scalable-couchdb-replication-and-change-listening-with-spiegel-878e22901dcd>. I hope this helps anyone else looking to scale designs like database-per-user.
I'll also be posting on how to get started with Spiegel very soon. Geoff
