Only with respect to amount.

That's a key difference.

If I can justify a /16 under section 4, ARIN will issue a /16, or, if they cannot,
offer me the choice between the largest block they can issue or a slot in
the waiting list (see waiting list policy adopted about a year ago).

Under 8.3, if I can justify a /16, since we removed the "as a single aggregate"
clause from 8.3 (and unfortunately due to an error in positioning, even before),
ARIN will approve an 8.3 transfer whether that /16 worth of space comes from
a single /16, 16 /20s, or 256 /24s or any other combination of /24s and larger
that make up that amount of space. This is current operational practice as
implemented by ARIN. One need look no further than the Nortel->Micr0$0ft
transaction to see clear evidence of this.

Sounds like a radically different form of internal problem.

It has not been my experience in dealing with several large end user
organizations that this always holds true, but, I would agree it is not

However, I'm not sure it's relevant to the debate on this proposal.
