It's not at all difficult to think of other reasons one might like a
static address. Some of the people on this list would like to set up
their own gateway/firewall/server system, not because they have
anything to give/sell to the Net, but because they want a machine
that they can experiment and learn on. There are jobs to be had doing
this sort of thing, but there's a major bootstrapping problem. You
can't get the job until you have the experience; you can't get the
experience until you have a job that gives you access to a machine to
learn on. But if you can learn on your home machine, you can break
the vicious circle.
Also, there are a lot of people who might like to put up a web site
with things like pictures of their children, their vacation, and so
on. This isn't likely to be a big deal web service; we're talking
about maybe a few hundred hits a year total in most cases, which is
hardly a load on a cable that's hyped as "lightning fast". Sure, you
can go through the grief of getting stuff uploaded to the "free" web
space at the ISP, but many users will rightfully respond very
cynically to this, if they've ever tried it. It's a lot easier (even
on Windoze) if you can just fire up a local web server, and point it
at the directory that it's to serve.
The neighborhood that I live in (Cedarwood, in Waltham) has its own
web page. I'd guess that it would not be what you'd call a major web
site. It's full of things like an announcement of a Family Fun day at
the neighborhood playground, various events at the nearby elementary
school, and so on. This would be a reasonable site to have on a home
machine. There are millions of such potential sites that are unlikely
going to turn into bandwidth hogs.
Such things hardly qualify as "services", and they're hardly a load
for poor little AT&T's wires.
Allowing home SMTP servers is an example that lightens the load for
the ISP. The amount of traffic to the home machine is exactly the
same, since each message is copied once in either case. But the ISP
then doesn't need to supply disk space to hold customers' messages,
and doesn't need to clean up after the messes that their own email
service inevitably produce (since most of them use a Microsoft email
package ;-). The customers get faster delivery, the ISP saves space
and time, and everyone wins. But this doesn't work too well if your
address is constantly changing.
My suspicion is that the primary reason for the clumsy way that M1
and other cable/dns services work is cluelessness on the part of
their management. We're talking about broadcast media and phone
company managers here, after all. Yeah, they hire knowledgeable
technical people, but those aren't the ones making the decisions.
