Noel's ideas were not tried.  They were (essentially) shouted down or 
ignored, take your pick.  There is a lot of merit in those ideas, and 
perhaps they should be resurrected.  The one fear I personally have is 
that the techniques he described have the risk of creating 
non-interconnected "walled gardens" overlaid on the network over 
networks.  That's why I talked about competing for *public* delivery and 
using the same common address space.
