    I'm frankly not that concerned about the pieces that I control, its 
the hundreds of thousands of end user devices that I don't.  In addition 
there are lot of pieces of gear that ISPs do control that don't have an 
upgrade path either because the vendor doesn't exist or the vendor 
decided to end of life the product.  I can tell you that most of the 
smaller ISPs still providing dial up, and yes there is still a ton of it 
out there, are doing it on old gear (much/most of that being Portmaster 
3s).  It's not that there isn't a solution, but it will be expensive and 
complicated and again that is before we include the issues with end user
