ATM as a LAN is probably ok, if it can compete with Gb Ethernet

Precisely my point, (which you managed to delete in your response).
Price/performance seems like a pretty good analysis technique, at
least for technologies that pass some basic hurdles, like "working."

FDDI is not a WAN technology. Losing 20% of bandwidth of a 10 ft
piece of fiber is one thing. Losing 20% of bandwidth of a
$3M/yr circuit is quite different.

I don't understand. Are you trying to say that price/performance
analysis is appropriate for LAN technologies, but not for WAN technologies?

Now, I could understand if you said, "I analyzed ATM WAN services for
one configuration once and concluded that other technologies provided
better cost/performance in all possible configurations," or even
"I don't think ATM products and standards are mature enough for my
application." However, you seem to be saying that wide-area technologies
should be assessed based on total cost and overhead, rather than on
