I don't see the problem that serious. This list server would only need to be queried by clients once when a user wants to register a new account which will not happen very often. Furthermore a failed query would not be fatal. Clients could just fallback to handling user-registrations like it is right now. > If it's desirable to have such a list, > why not federate it amongst all the XMPP servers?

Of course a list server does not have to be a single instance (as I wrote in my initial proposal). Nothing has to be restricted or forced in any way. If someone wants, he could just setup his own list server. Sharing information between list servers then is a logical feature. > XMPP is often compared to e-email when one wants to describe the > federated nature.

I agree with you basically and guess that if XMPP would have evolved sooner (i.e. before WhatsApp), the situation today would be different. There would be more good and well-known XMPP servers and the decentralized concept would be just a normal thing. Unfortunately the simple fact is that WhatsApp spoiled the users: A) Install (Whats)App, verify code, select contact, write message. is much more easy than B) Install XMPP-App, choose server, enter desired JID, add contact button, enter contacts JID, select contact, write message. I see a problem with "choose server" right now, because: - Not every client developer wants to setup and maintain a good xmpp server by himself (ChatSecure for example). - Not every XMPP server is a good choice for the user. So if someone decides to not use the developer's server he needs to get further information, understand what MAM, Push, Stream Management, etc. means, find a server that supports that and register there or get that information from someone who explains this to him. Even the need for explanation is a bad thing here! People can use WhatsApp without the need for any explanation. Why should XMPP be different?
