Indeed. "Brittleness" is what's making the creakiness of the Net all
the more apparent and critical every day. (Some things it does very
well, and I'm amazed that it works as well as it does...a lot of
clever people out there making patches.)

Software has been compared to building a Boeing 747, except that
flipping one little switch accidentally can make the wing fall off.

We see islands of relative stability (word processors, apps, etc.)
separated by flaky, error-prone (human, mostly) networks, with little
interoperability.

We mainly do "encryption" and "remailing" with our wonderful crypto
tools--and we *don't* do much of the other neat stuff that is
possible--for a simple reason: the only thing all of our myriad mail
systems, newsreaders, various platforms, and communication systems can
reliably communicate to each other is the _simple text message_!

Although much more complicated objects are in principle
intercommunicable (and Mosaic can do images, etc., so things are
changing), the basic object of communication is the text block. It can
be encrypted/decrypted, signed, and remailed, with people at the
receiving end knowing how to handle it....that's why PGP and remailers
work.

The other protocols rely more on complicated objects, signals sent
back and forth, and are much less interoperable and semantically more
ambiguous.

I agree. If the meeting is still on the 14th, the normal "second
Saturday," I'll be there. If it's been moved to the 21st, as was being
talked about, I'll be down in Los Angeles (where I'd still like to
meet with any LA-area Cypherpunks who wish to meet).
