	all too true - an entry in the RIB/FIB is an entry. the "size"
represented by the entry is immaterial as far as the routing system goes.
but consider this:

	so for that /48 that your are injecting into the routing system
do you mind if i "spam like hell for 10 minutes" and forge the source
addresses as a random spread from within your /48?  you get to eat all
the bounces and complaints - right?   hope your bandwidth is big enough
to swallow the fallout. :)  in this context, size does matter...
