That's the most noble thing to say and all the reason why
asynchronous messaging was invented in the first place. :)

A lot about GNUnet and related projects hasn't changed dramatically
in the past fifteen years. We had our vision laid out even before
Snowden and suddenly became relevant, so there are many worthwhile
videos from around that time. Here's some stuff:

The one on scalability discusses multicast technologies. I had a
business doing scalable chat systems before Zuckerberg used ruthless
methods to gain market dominance.

No, I was thinking of things such as chatrooms and broadcast
channels. How do you implement those if you don't have a server
in your toolset? secushare contains much thoughtwork on how to
do these things while reducing dependencies on certain servers
to stay up. If you use this XEP to connect two clients to each
other, what can they do? Just send stickers at each other? It's
a bit meager an earning.

Have a look, it's especially dramatic when embedding binary data:

Not sure how well existing libraries abstract involved headaches away.
When it comes to dealing with radio and its protocol implementations
you might find yourself spending a lot of time dealing with glitches
and things that should be working according to the docs, but don't.
But once it works it is obviously very useful to have. The way any
GNUnet node should be able to work with any other should at least
avoid the whole pairing business. Ideally simply flicking bluetooth or
wifi on should allow your locally running GNUnet node to exchange
traffic with other nodes in the vicinity, in theory.

For completeness I should mention that I was involved with the
implementation of one of the first Jingle/WebRTC libraries
together with my former employee Philipp Hancke.

It expects that an XMPP server exists and will not go down
or become unreachable randomly. In GNUnet/secushare we
intend to use distributed storages and strategies for that,
so that chatrooms and mailboxes exist in a "cloud" of
distributed nodes, not in a replicated database on corporate
servers.

Again, same server storage problem. So if you consider that
all the server-based functionality isn't working, what's
staying is the 1:1 stuff. Is it worth all the disadvantages?

If this stuff actually works and solves some problems, this could be
a useful thing to bring to GNUnet. It's not the first of its kind
and the usefulness of actual mobile code rather than shared
specifications isn't endless, but for some purposes it may work out.
First time I heard of such an approach was in 1990. BuGless suggested
we should have a mobile programming language for chatroom conference
control so that the way the chatroom works can travel across the
network in form of a programm rather than a specification. The idea
was radical and fascinating, but having protocols and configurations
always ended up being good enough or better for all purposes.
Also reminds me of Ethereum's idea of doing DAOs, a method to me best
known for its bugs: a DAO hardly ever does what the original author
intended it to do. In real life the author remains legally responsible
and can fix the bugs, in Ethereum anyone who invested in the DAO now
has to deal with whichever consequences.
So 34 years later I'm still excited to see if such an approach will
lead somewhere...
