[JM] Besides filling out 1500 requests, waiting for 1500 tickets to pass
justification, filling out 1500 RSA's with the correct ticket numbers,
and paying $750K upfront and ongoing maintanance to ARIN, what added
benefit would "the Limited" get for using public ASN's in this
presumably non-Internet use case?

[JM] Since they seem to be in NoVA, just did.  "Sue" at the ARIN
helpdesk clarified that each request would have to be justified
seperately with diagrams, there are no block assignments, and that she
had not seen a "unique routing" policy justification fly in the many
years she had worked there, only multi-homing requests go through.  She
recommended for the scenario I laid out that I use private use ASNs.

I think what you are proposing is a huge cultural shift / re-education
on the definition of appropriate use of public ASNs, which is certainly
possible but I'm unclear the value proposition since I'm thinking the
existing private ASN's deployed are not going away so we will have to
deal with this new way of using public ASN's for non-public applications
as well as all the knobs around AS_PATH manipulation for overlapping and
private ASN removal as well.  All my proposal does is allow individual
organizations to grow beyond the current range, it does not aim to
address the difficulities of connecting various organizations with
overlapping private use ASNs.
