I do like this. The next part I'd like someone to build on top of this is applying the stream 'events' into a point-in-time queryable representation. Basically the other part to make it a Datatomic. Probably better if it's a pattern or framework for making specific in-memory queryable data rather than a particular database. There's lots of ways this could work, like applying to a local Sqlite, or basing on a MySQL binlog that can be applied to a local query instance and rewindable to specific points, or more application-specific apply/undo events to a local state.
