I think that some care needs to be taken here. We know well that the
internet (and telco, and TI) market is largely buzzword driven. From the
customer point of view, and from the provider´s as well. People are
often pushed to believe they need tnings that prove useless with time.
We should also not underestimate the conservativeness of customers. I
think that much of what is called "user needs" is in fact no more
than a reaction of customers against the new communication pradaigms
the Internet propose them, a desesperate attempt to make the new tools
behave the way they are used to.
An exemple: we see a lot of companies buying VPN when all they needed
was N (network). Not totaly useless: at least the telcos make a lot of
money selling people an "enhanhed quality" connection that, most of the
time, if not all the time, will behave exectly as well as an ordinary
I am stiil a believer of the old dream. :-)
I admit that there is a "real world", made of people that will not
sleep well if they cannot see the circuits in what they sell and buy.
This is not a real world to conform to. This a world to change.
