I do think they have a point, though; ECN is listed as an experimental standard at IETF, and I do think that it's not exactly fair to *require* everyone to use it until it is standards-track. It would be another thing if Linux could turn it off on a per-connection basis if these packets get dropped. In general, I have found the Hotmail people to be quite responsive to problems as long as they gets pointed out that they violate established standards. In this case, though, they feel that they don't want to potentially destabilize their network over something that is labelled an experimental standard. I can certainly understand their point. -hpa -- at work, in private!
