I came up against this when a client nicely asked about jumbo frames on his shiny new Cisco 3560 switch - and none of his computers could agree on anything greater than 4k. And, to make things worse - a few of the drivers wanted to enforce certain values rather than any value between 1500 and an upper limit - making the whole feat impossible. Yay for non-clear specifications. The skeptic in me says "ain't going to happen." The believer in me says "Ah, that'd be cool, wouldn't it?" The realist in me says "probably best to mandate that kind of stuff with the next revision of the ipv6-internet with the first few bits set to 010 instead of 001. :) The real uptake limiter is the disagreement on implementation. Some of you have to remember how this whole internet thing started and grew (I've only read about the collaboration in books.) Adrian
