Yeah, but that behaviour is a BUG --> it will be corrected.

Do you know XMPP transports?
The problem with such extensions is that someone has to maintain them. Its useless to have a "WhatsApp" transport which do not work because of protocol changes.
But if we're discussing alternatives to the closed, central networks, I wanted to point out that there *is* something in between central and p2p (namely, federated); and an implementation of such a network which seems to be Done Right (namely, matrix).
And this in-between thing exactly answers the problems being discussed here with p2p (namely, transmission of messages when one of the parties is offline...).

No, because: Such general statements are mostly wrong.
Seriously: If you want to go "off the record" use the ORT functions implemented in most messengers that are out there in the wild.
And still providing message delivery if the contact is not online at the moment.

You can never trust the transport way, not even if the service is running on your own server.
And yes, there is something like OMEMO (double ratchet) which allows sending E2E encrypted messages to offline contacts. This is well documented and already implemented in XMPP clients:
https://conversations.im/xeps/multi-end.html
Of course this opens a new attack vector since the keys are cached on the server.
All this will be also made for matrix to reach the same privacy level which is already done in XMPP.
Don't get me wrong - its great people wants to implement new, open and secure conversation systems.
But at the end, the only difference between XMPP and matrix will be the protocol layer: HTTP/JSON vs. XML. And I prefer XML :P

Yes, that's the idea behind OTR, if you and your contact go OTR the server is left out.

Are you sure, you understand the technology?
a) I was criticising that with Ring you can't reach offline contacts and messages go to waste.
-> you reply that p2p / serverless chat is "the only solution"
b) I reply that OTR is also possible with existing messaging applications using server infrastructure. Encyrytion yes/no is not the topic here
-> some bogus from you
Sorry, end of discussion for me here.

All popular chat solutions today are unusable.
They all use a central server instance which can be hacked or controlled by individuals who wants to read my private conversations.
Only p2p messengers are usable - as of the status of today.
Got that?
