Now the ISP could indeed assign a /52 per customer, which means that
/40 would provide for assignments for 4 thousand customers (and at 
/56 per customer, well, they can serve quite bit more from /40...)

If we keep them serving 1024 customers, then a /40 provides them with 
the ability to serve all of them using /52 size assignments, and an 
ISP that feels strongly that a /48 is more appropriate for assignments 
could opt for a /36 allocation, and move up to the x-small category 
at $1000/year 

(In either case, they are paying _far_ less than today's fee schedule 
for x-small which is $1250/year if they don't have IPv6, and $1687 per
year if they do.)
