I'm aware that routing table bloat is a problem, I'm also aware that just doing what we do today tomorrow will probably cause lots of expense, failure, or pain at some point in the future. I can't see that source/dest pairs being basically meaningless and large sinks or sources of traffic being anonymous is going to help either. (shim6 provides the possibility for end nodes to 'renumber' and change their source/dest at will, potentially playing havoc with traffic patterns, potentially even inducing 'failure' in the network interconnects along the way. > > > > agreed, but it doesn't seem that, until recently atleast, there was > > much > > operator participation.
