Touche, that's easy:
You just made an argument for ATM to the desktop... [since the WAN was ATM].
There are those who thot the whole ADSL implementation should have been with an
ATM NIC - no ethernet!  This was the early preachings of Alcatel.  Unfortunately
our American (that's us) providers told us that Ethernet had already won the
desktop war and that nobody was going to buy an ATM NIC card for $300 when they
could buy an ethernet card for $30.  So there you have it, ethernet in the LAN,
ATM in the WAN [of course I'm simplifying here], and we will live the consequences
for probably a generation.  I think Ameritech actually started ADSL with an ATM
NIC a couple years ago.

Question posed to Arthur C. Clarke:
How do you keep up with the new advances?
"I don't, of course - who can? And it makes me sorry.  I can't read fiction
anymore, I just don't have time for it.  The entire time is spent e-mailing!"
