Uh, no, ECN is not broken at all. What is broken are all of these
routers that depend on reserved bits in the TCP/IP packets. ECN itself
does not break things, it merely shows other things that are broken.
If we left everything to "you have to be smart enough", then let's just
leave out the entire linux kernel, most of the software in Debian, and
go for a minimum cygnus install. Let's just ditch all non-i386
architectures. Hell, let's get rid of everything that might potentially
break your system, unless you are smart enough to use it. You know,
things like X that can fry a monitor, or mkfs that might trash your

If we did that, then maybe 4 people would be using it (there's not many
people in the same class as davem).
This needs to be pushed to the masses. If we watited for all of these
vendors to fix their equipment, and all of these corporations to apply
those fixes, before spreading ECN, then DaveM might be the only person
who ever uses it, and nothing will get fixed.
That fact that things get broken, and people complain, is one reason
that things get fixed.
