[address-policy-wg] applicability of a request for 60000 IPv4 addresses/systems in one shot...

Dear all,

I am a member of a -yet unofficial- effort in Greece,
where we are in discussions on the potential of using
Greek School Network resources (calculated at >62000 machines)
with a scavenging technology developed in-house by NTUA
[ref. http://gridathome.sourceforge.net/ & http://www.ntua.gr ]

The idea is quite simple: you boot your systems or Virtual Machines
with a LiveCD, you get an initial -normally private- IP address, and
*then* a public one from a VPN tunnel, with which you implement and use
full grid functionality because there's end2end network connectivity.

Yes, there is a catch: this scheme requires extra publicly routable address
space, if it is to be integrated with the existing grid infrastructure
(and there are plenty of good reasons to do so, for us and others).

I've been looking at http://www.ripe.net/docs/ipv4-policies.html
and it appears to me that "Assignments for Internetworking Experiments"
would be viable option to begin with but, under what conditions can we
request standard address space for, say, 60000 PCs or Virtual Machines?
What should we make clear in order to make this successfull in one shot?

ps.
Note that currently these resources lie within hundreds (thousands?),
of NAT'd networks, in a multi-tier network. Our LiveWN technology can scale
extremelly quickly, much faster than commitees in schools/government. :)
The reason I am asking you is because we are about to prepare a TDR,
Technical Design Report, and wish to confirm the validity of our options.

ps2.
at current stage IPv6 is not an option due to grid middleware limitations.

thank you in advance for your time,

Drs. Fotis Georgatos
