This "honesty" coming from the person responsible for taking somebody elses 
ip block (hijacking four old micro-assignments in fact) is very interesting...
(for reference, see http://www.completewhois.com/hijacked/gang_ings.htm). 
Obviously you have no problem lying to ARIN either about ownership of ip 
block or in the future about size of ip block you may need. Unfortunetly 
policies created by ARIN are all designed based that people using them 
would be fairly honest (and if this is a problem - we can work on it).

Hopefully, not as many as you Jeff Wheeler thinks (do not ever assume
everyone else operates the same way you are). I can tell that all companies
I've dealt with that have /20s all had enough use of those ip blocks and 
have not exadurated numbers when getting them.

ARIN is already very difficult to work with (and this is topic for 
completely different discussion), the current proposal for 2002-3 will not 
change difficulty in working with ARIN. If anything on that issue I support
ARIN being difficult and doing hard checking about micro-assignment requests.
