I believe buying and connecting thousands of $10 modems to register with 
a DHCP server actually constitutes valid use of IP addresses. You would 
more likely need to create a script to spoof mac addresses in 
registering with the DHCP server over time to be in violation. Works 
about like a script that pulls names out of a phone book and assigns 
them to IP addresses in a report. The difference between the two is that 
it's easier to make the report than create a good dhcp script that will 
also utilize bandwidth and multiple interfaces or fill dhcp snooping 
tables and show up interfaces.

The reason I'm completely for skipping all the extra paperwork and going 
straight to a meeting session is that it's easy to view the various 
screens depending on the ISP layout to show that a group of addresses 
are in use and much more difficult to cover all bases to defraud ARIN 
(not impossible, but much more difficult than forging customer names).
