Categories should not be based on who you are (home, SOHO, enterprise)
but rather on what you do with the address space and your justification
for it.  I don't think it is rocket science to set some criteria around
number of hosts, number of subnets etc. similar to the current

A very simple (and no doubt inadequate) set of categories would be:
  - 1 host (are we really talking about global routing entries at this
  - 1 subnet (um, what size?)
  - 2-5 subnets
  - 6-20 subnets
