"The time" was 1984, the same time I introduced the packet BBS.
One caught on, the other didn't. Why was that? Ease of installation and use.

"... awakened them..." to what? I think all hams interested in building and
using RF networks are well aware of the problems. The high speed modems
available simply cost too much.

$20 for a 56k V.90 modem at CDW and several other mail-order places.

Nothing out there at all. Zero. Zilch.

There is also the problem of software that runs on Windows, is easy to

Even if Joe Ham were interested in tcp/ip, he doesn't want to spend weeks
trying to get some arcane software running. He wants to USE the software,
not play with installing and configuring. There is none available yet that
meets
these criteria.

Error correcting would be useless in PSK. It is too slow to spend the extra
effort and for that reason is usless for binaries, so why bother?
PSK is and will stay a keyboard to keyboard or it will not be what it is.
Now a WIDE band versiin might be something to think about but that is
another
story.
BOY I hate using someones AOL with no spell checker for newsgroups!

I think you are completely wrong here. Anyone can develop applications
that use today's webserver/browser technology, which is layered on top of
TCP/IP. It is simple to write perl or php scripts that run on Apache, or
scripts that are run by Roxen, or on Microsoft IIS.
The fact that this is so simple is because the entire protocol stack
is standardized from the IP level up, and in wide use on the Internet.
Hams can transport IP trough their network (as far as it exists).
No similar capability exists for bare AX.25 networks. Of course it could
be built, but it would automatically mean having to design both servers and
clients. Sure, amateurs have done this. But today it does not look like
the way to rapidly improve the application situation.
