I think there are two approaches one could take for doing this:

* It seems like one way you could make that possible would be to make it really easy to do white-label builds of the Zulip mobile apps. E.g. the "Zulip for example.com" app. Would be more overhead than is ideal for smaller deployments.

* It should be possible to have APNS/GCM traffic go through a central community-hosted service that dispatches the messages on to a set of configured Zulip servers.

We actually had functionality based on a similar concept for the Zulip desktop app login process, where it would query a service on zulip.com with e.g. "example.com" and that would return the URL of what zulip server hosts example.com, so that users don't need to fill that out in the login process.

For the open source release, we replaced this with in an explicit "what server are you doing prompt" but it would certainly be technically possible to go this route.
