But FDDI has a *great* admission-control scheme.
However, I almost concede your point. :) [*]

No kidding.
Sean.
P.S.: [*] almost, because in an application where one is
using ATM as a single point-to-point PVC along a
long-haul trunk that is to be used essentially exclusively
for IP traffic, the cell tax seems really excessive.
Given the movement towards cisco's packet-over-SONET,
should that work and should others implement similar and
preferably interoperable point-to-point interfaces, I will
have to withdraw my almost-concession, except in cases
where people _really_ want to do point-to-multipoint stuff.
