The space people 'need' is only one side of this discussion.  The structure 
of the routing table is another issue that cannot be ignored.

I do not think anybody is disputing the point that provider independent is 
easier for many reasons.  However, addresses are addresses, and while 
renumbering may be annoying it is really not that difficult when you 
structure your system properly.

The key here is that we consider all of the issues surrounding ARIN's 
minimum allocation size.  If we just focus on people lying, how much of a 
pain it is to renumber, or the routing table structure individually then we 
will not come to a conclusion that satisfies all of the issues.

Well getting accurate data on that would be tricky.

I'm curious, where do you get your data on this (internet growth and 
address space utilization)?

Also, RIPE uses a very different system for allocating addresses, every 
time a RIPE LIR wants to make an assignment you have to get permission from 
RIPE (Cathy Wittbrodt calls this the "Mother May I" system).
