Yes, I could have phrased that differently. I just find it strange 
that non of this was thought about way back then - but perhaps none 
of the people who this affects got involved.

I agree, now is "too late" - I think a lot of what we do would be 
different "if we knew then what we know now" ! Who knows, if someone 
could time travel, would we ever have started with 32 bit IP 
addresses ?

I guess, back then I would have thought along the lines of "I'm only 
a very small user, and I doubt if I can bring anything to the party 
that other users already are - apart from more noise !". Perhaps too 
many take that attitude ?

That would be interesting to know ! Perhaps I'm a bit too cynical at 
times, but I don't hold much hope that certain big vendors are 
listening. My cynicism comes partly from working in a "Windows shop" 
and getting to quietly observe how some of it works (or doesn't!) - 
slowly plugging away to bring enlightenment to the rest of the team

No, no witty retorts. But it does remind me of the old joke about the 
traveller asking for directions, only to be told by the local "well 
if I were you, I wouldn't start from here" !
