Well, I guess, this is the price we must pay for having a monoculture
(a Cisco-powered) internet. If the single source of routers, switches
and network components (speak: Cisco) makes a single mistake in a
release version of their software (speak: drop ECN frames), everyone
suffers.

Cisco: If I buy a _new_ PIIX oder LDIR today, do I get an ECN capable
IOS or not? If not, will my CCNA know about this and upgrade my Box
before deploying?

Everyone I know and their brothers, that use Cisco Equipment, have a
support contract with Cisco. Why not push an "mandatory upgrade" along
this path once the ECN leaves "experimental" status.

But I definitely agree with HPA, that forcing ECN in its current state
on all users is unacceptable.

Solution that I see: 

DaveM at RedHat ships Kernels with ECN enabled per default.
RedHat ships Distributions with net.ipv4.ip_ecn = 0 in /etc/sysctl.conf

Ah, the small bliss of diversity... ;-) (And this means not, running
both flavors of Linux, Debian _and_ RedHat... ;-) )
