   If you cannot estimate the number of potential users since flat cable 
network have so many "home passes" but so little real users, the only way 
to control this is by checking subscriptions per head end.  This is nothing 
different from checking PPPs per Broadband RASs.
   It is too simple to estimate number of users by maximum capacity per 
head end since the subscription/home pass ratio is too small in typical 
cable operators.  To make it fair, if you adopt this strategy, you should 
assign IP addresses to DSL operators based on number of telephone lines in 
central offices since "home pass"="potential users per head end" and 
"number of telephone lines"="potential users per central office".
