Does anyone still have this program?
If so, if I sent a blank floppy with a return SASE plus a couple of bucks
for your trouble would anyone be able to make a copy for me?
Thanks & 73,

I think it's an uphill battle -- if you know some ways to go about
attracting young people into the hobby I'd love to hear them.
I'm 22 and know plenty of people who could pass the theory and regulations
exams without doing too much study at all (engineering majors). The
interesting isn't there though. I don't know anyone my age who has
their full license. The local club has a lot of guys who are younger
(pre-retirement!) but still 30+ I think. I find this a bit of a shame
because I get a lot of fun out of this.

Right. That's exactly the correct approach. Hide all the magic in sendmail,
or an equivalent daemon written for Windoze invoked at system startup,
and in the low level protocol and device drivers for each type of interface.
At the user level, implementation details should be invisible and irrelevant
to the functioning of user level services.

Right. Netmeeting, and other whiteboard conferencing programs, do work
well on a 56 kb network. They really bring the benefits and power of packet
to the forefront. Digital voice programs such as i-net phone work too, though
currently they are more a curiosity than useful tool. rlogin also works for
access
to distributed computing resources. Other more sophisticated client server
and distributed computing activities are also feasible. They just can't work
well at lower speeds due to throughput and latency problems, so until the
RF infrastructure is improved in an area, they won't see much use.

It is primarily a political (and financial) issue. RF networking requires
cooperation on a scale that's unusual for amateur radio. It also needs
an infrastructure whose cost has to be borne by the network users
in an equitable fashion. Few amateur groups have managed to pull it
off at the LAN/MAN level, and fewer still have managed to implement
and support a WAN size system.
I'd also agree that something a bit more user friendly than sendmail
scripts, routed, and ifconfig would be nice so that a user can get up and
running without having to know all the cryptic details of configuring to
work with a given network. (This has been getting better. Many of the
recent Linux distributions have setup menus which make these tasks
much easier than they were in the past when you "just had to know" to
be able to set things up.)
But each amateur does have to act as his own "ISP" in most of our
networks. That means he has to have knowledge and skills similar
to those required of people who administer landline ISPs. It isn't
"plug and play" the way a dedicated single user wireline internet
connection via an established ISP is. It probably can't be made
"plug and play" given the nature of amateur networks.
