For an person prone to abstraction, there's little more
baffling than chat implementations. It could be extended to
voice and video calls as well -- after all, what major
company doesn't have some offering these days -- but for
now, let's stick with chat. Consider:

AIM, Bonjour, Gadu-Gadu, Google Talk, GroupWise, ICQ, IRC,
SIMPLE, Sametime, XMPP, Zephyr.

That list alone comes from Pidgin (https://pidgin.im), a
single chat application that tries to run them all. Go
further, though. Think: Twitter, Facebook, Instagram,
Diaspora, Freindica, Mastodon, Pleroma, SMS, iMessage,
Session, Semaphore, Signal, WeChat, Element/Matrix, Threema,
Telegram, StealthChat, WhatsApp, Wickr, Viber, GroupMe, Tox,
Slack, Discord, Hangouts, Messenger, ...

You'd wonder if consumer technology was used for anything
except for this. Are you working on a new chat app? A new
architecture for a chat app? Trying to make them
interoperable? Trying to make users discoverable? Trying to
make the signal channels more secure? Maybe you actually are
doing something else! Don't worry: it's just a matter of
time until someone presses you to make it "social"...

Anyway, if you're a truly abstract thinker -- maybe a
systems engineer or architect, a systems integrator, a
requirements analyst, or some othe individual charged with
decomposing things or putting them together -- this is where
you know to keep you mouth closed and slowly back away. Why?
Well, you know The Truth(tm): The are all the same.

Sure there are a couple of variables -- a Chinese Menu of
options: Public or Private? Group chat? Encryption?
Presence? Both parties online? History storage? Searchable?
Plain text? Rich text? Multimedia? Amplifying, repeating,
alerting? Threading? ...

Special sauce, huh? Sure. You want fries with that?

It's tiring, but somehow it never gets old. It sure sells
cellphones, though, no?

Anyway... RetroShare:

It uses gpg-based public key for identity.  You advertise
your identity, location identifier, and public and private
ip addresses and ports to your peers. Yes, you explicitly
tell them who you are and where you are. You must
affirmatively confirm each other as friends. Afterward, you
may have access to friends-of-your-friend and vice versa.

The service relies on hole-punching out through your
firewall so that messages can come back in to you. If you're
in a fixed location on some network and you have access, you
can make that nicer via port-forwarding to your client.

If you want to to hide your address, there's Tor and i2p.
From the Tor perspective, if you're also running Tor locally
(i.e., Tor SOCKS proxy), your vanilla "node" can talk to a
Tor node. As you'd expect, Tor nodes (hidden services) can
only initiate contact to other Tor nodes (i.e., no exit node
use).

What does it try to do? Instant messaging, presence,
broadcast & group chat (IRC model), file sharing (like bit
torrent), in-network email (seriously, theres' an email
client window), forum posts(?), and others. It's the kitchen
sink -- the whole shebang.

Technically, if it's doing anything unique, it might be that
it's trying to do that server job that can be daunting to
set up if you lack the skills, and for that matter it's
trying to do it like you're just a client -- assuming no
access to the firewall, router, DNS, and so forth. Technical
folks know that that is just shifting the burden to
somewhere else -- in this case, it's to the user with the
funny "ID" values (containing your actual ID information as
well as your network addresses). I expect that as you move
from location to location (i.e., from network to network),
that probably becomes tedious quickly if you want to add
people outside you clique or if multiple nodes are mobile.
There is some kind of extra routing and discovery going on
in there -- I'll know more soon enough.

And to be sure, until you're peered with some friends,
figure it's a lonely app. I haven't checked yet if there are
larger, populated open servers hosting larger groups yet.
Why not? Well, installation had a few issues... and
documentation was a bit behind, and ... and ... and.

But in the back of my abstract thinking mind, I know I
should probably just be quiet now and step back slowly. I'm
not sure who this helps. I'm not sure it makes life easier.
I'm not sure it fills a gap. Who knows? It's TBD.

If you want to give it a go, let me know! You know, through
some other means of contact... because I'll have to start up
the VM and the service, check my current ip addrs / user
address, share that token with you out-of-band (since we
can't communicate until we're both mutual friends), ...

Like I said, I'm going to be quiet now :-p
