Fixed Boundary (/29) Assignments

=> IMHO, no.  Why should the amount of address space assigned have anything to do
=> with the way that a network is connected to the outside world?
=
=I think the important bit is the word "residential" and not the
=connection method. 

  For the moment I cannot see clear-cut criteria to label one network as
  residential and another one as [implied from context] business, and to
  do so consistently over teh life-time of the connection/network.
  
  Which IMO makes that aspect useless to base address distribution
  policies on.
