well, the telegraph led to the fax (yes, really) and later they came
up with the teletype.

Everything since is pretty much elaboration.

Well, even then there are limitations. Even if range is unlimited,
you *can't* connect to everybody. So mail will get forwarded. and
quite likely via something like the early internet/usenet "bang
paths" (basically the "address" line is a list of nodes to route
thru) This isn't as nice as domain based addressing, but it allowed
you to *deliberately* route around nodes that had problems (or that
you had reasons to not want your message to pass thru)

"News" (ie messages aimed at anybody who is interested) works
differently. You'll want to organize it by topic/subtopic etc (like
usenet news, and fidonet groups).

In the OTU, neither is a big problem. In variant TUs with lots of
alien starfaring civilizations, it gets a lot weireder until you have
Vinge's "net of a million lies" from "A Fire Upon the Deep". among
other lines you *need* stuff like his "Language-path" header as
messages get translated and re-translated along the way.

Sounds like the linked "wormholes" Laurence Dahners uses in his Ell
Donsai stories. They use the paired "chips" *mostly* to connect
devices to switching units (much like a telephone exchange) which
then connect it to whatever other device you want to contact.

Yeah, that does have the problem of somebody blowing up an
exchange/server and rendered all the devices that connect to it
useless.

But smart folks will have connections tpo multiple servers *or* a few
*direct* connections (think leased line phone service) that don't
*use* the servers.

Also, since both the "wormholes" and quantum entanglement are *by
definition* undtectable/untraceable you only have to worry about
destruction of the "server" if the links are server to server, rather
than device to server.

For small "link" equipment, you'd go with device to server and only
the folks providing the service know where the servers are.

For "large" link equpment, you'll use normal methods (radio, cables,
and the like) to connect to the servers and only use the ansible
links to connect *between* servers.

That *does* make the servers a point of failure. Which is why you
take a tip from the way the Injternet is set up. You have all the
servers connect to multiple servers. So taking one out means you've
only isolated the folks connected to it.

Everybody else just continues on because they can route thru a
different server.

That sort of thing was one of the design criteria for the ARPAnet and
for the Internet that grew from it.
