Any reason for that? It's also doesn't look very straightforward how exactly the database is deployed and accessed on the server. As it stands now only the 'client' is open sourced but if someone wants to hosts its own `realm` database it still has a lot of work to do. I really find this misleading when various SAAS vendors claim they are open source when in fact they just provide you just a client to access their service. Nobody(almost) would use a `binary` client anyway.
