There are two reason why I believe that separate maintainer IDs are not
really workable.  1) Administrative: Multiple maintainers would greatly
increase ARIN and our administrative load due to the increase in number of
address requests that would need to be processed.  2) Cost:  Why should
some organizations pay multiples for the same amount of address space?
$40,000 for 16 /20s vs. $10,000 for 1 /16.

This is workable alternative for smaller organizations, but under the
current fee schedule there still is a cost issue.  This also wouldn't
apply to some since in most cases they would be able to justify an initial
/20 from ARIN for each routing domain and we are back to where we are now.

I totally agree this isn't ARIN's problem, but as long as some ISPs choose
to limit their route-table size by using a RIRs allocation policy as a
filter we will have to deal with the issue.  What good is an allocation
that isn't routable?  Perhaps time is better spent on making
proxy-aggregation workable to help alleviate route-table growth.

While this would work with networks with a backbone, I fear it may cause
more additional routes to be injected into the table.
