This looks interesting, but in practical terms we would need a document model that maps client data to endpoints on the server, with the understanding they might not be similar. The data the client associates with a user might not necessarily match the server's modeling, for example.

In other words, the client should still be decoupled from the server. But PouchDB looks like it has the right idea on the client.

edit: I realize I Just kind of described an ORM. Sorry.
