Well, it seems to me that you are proposing an independant proprietary
network addressing scheme.

Since this is, by your own definition (it would appear to me) independant of
the Internet, then I can't see the problem in simply using the 10 block and
maintaining an independant record, one IP per defined organization. The
organization could presumably just NAT from their network into yours.

There's a reason for that. Well, several really.

That's still proprietary, by my lights. Doesn't really matter whether it
uses IP, baked bean cans and bits of string, or whatever. If you're
enforcing some sort of access policy, then it's private. Period.

Given that the vast majority of companies are moving away from precisely
that sort of scenario to the public Internet, I can't really see people
investing in such a thing - while it's fine for defined circumstances (e.g.
dropping the serial lines to the LSE as part of the Sequence program in the
mid-90s), but I personally can't see it as anything but a policy reversal.

IIRC, Radianz were the Reuters spin-off when they decided to cut costs -
post Bridge and Instinet - and flog HPSN (if I recall the name correctly -
it's been a long time), under the tutelage of Dave Ure (again, if memory

Reuters themselves moved away from the fixed-connection Monitor network into
IP, and, IIRC, provided DEC PDP-8 based units to allow NAT access to their
(supposedly!) low-latency network by customers. [I say "supposedly" because
a 30-second delay between the old switching centre at Singer Street and
Singapore Editorial was more than a bit inconvenient in a VT320-based

I would suggest that your target customers would be best served by a
consortium-led directory made up of the main players in the industry, and
that - therefore - this isn't really a valid topic for discussion here. I
personally see it more akin to synchronising POTS telephone directories than
something requiring the formation of an independent international body.
(Obviously, I'm more than willing to listen to other opinions on this).

Please feel free to take this discussion private, should you prefer..
