William and I both presented at a RethinkDB meetup this last fall (SageMathCloud leverages RethinkDB changefeeds in awesome ways) and I got to talk to him a bit about some of these frustrations. It really is a rough spot to be in and I wish him all the best.

Every time a user types anything into any document in SageMathCloud, RethinkDB changes propagate those changes to all other users of the document. We use RethinkDB heavily at all levels of SageMathCloud.
