Yes and yes.
No one can think of any high bandwidth applications except video - perhaps mountaintop
wildfire cameras, etc. Good in California...
Hams just don't generate a lot of data. Many are content to fool around with 50Hz CW
or various digimodes. On 3400MHz!
I was interested in New Packet Radio at first. But there are no applications which would
use even the soda straw 50kHz bandwidth on 70cm in US
Also the NPR primary folks seem intent to recreate IPv4 badly. The radio is a modem, a
layer 2 device. IP is a WAN protocol, not at all optimized for LAN work. They should
have looked at prior art of LAN protocols, IPX, Appletalj, XNS, etc.
So for me as a professional network engineer, I'll pass.
(I feel if we had compelling high bandwidth applications, we could have better justified
our 3400MHz allocation...)
Thanks for indulging my digression.

I don't see how deploying some actual

buying into a system that's oversubscribed by design and you're at the

The other consideration is that right now, practical use of 44Net
address space is limited by all of the technological hurdles you
already summarized so well. If we deploy an easy-to-use system that
support things like a single OpenVPN connection for an endpoint or
easier tunneling, then usage is likely to ramp up quickly. Having real
systems designed in an "enterprise" way actually cuts down on user
support problems later on or the need to redesign-on-the-fly as you
grow. No one wants to be trying to rebuild the plane while it's in the
air.
One of our problems is that we have a hard time coming up with a use
case and
killer advantage of our own network compared to the normal internet.
One of the few hard advantages we have is the availability of large
numbers of
IPv4 addresses for free. That enables us to run a network with clean
routing and
subnetting and without NAT. Once we would migrate to IPv6 we would
also lose
that advantage.
So, there really is no large influx of new users to be expected. After
all, why would
you connect your system to 44Net unless you already are a networking
buff that
would like to run services at home and play with networking. Not so
many radio
amateurs are. In our country with ~13000 registered amateurs (and pop.
17M)
we now have issues 244 OpenVPN certificates over the 6.5 year period
that service
is now up and running, and about 25 of them are usually connected.
We also have about 125 AS numbers for routers around the country, and
about
170 subnet routes being distributed via BGP (plus those for the VPNs).
That is a scale where software solutions like Linux VPSes either bare
or with a router
oriented OS+Configuration like MikroTik RouterOS still works perfectly
fine. We are
not to be compared with an ISP with millions of subscribers.
Actually using VPSes instead of hardware makes it easier to ramp up
(and down)
quickly, as those providers normally have very convenient mechanisms to
deploy
new instances, which beat truck-hauling hardware around the world every
time.
Also when you use VPSes from an external supplier, it is them who are
looking after
the hardware, replace the broken fans and disks, and replace the entire
machines
when they become obsolete.
I think the only work we would need to do ourselves is to make a
network design
and base configuration of the equipment, and likely make some tools to
assist
in chores like adding a user account or a new node in the network.
(doing reconfiguration for that)
Some people come up with the "disadvantage" that relying on a VPS
provider would
mean that your network is less reliable because you rely on some
unknown external
party. I think it is not so bad because we can always decide to use
VPSes from
different providers, and even when you provide your own hardware you
will still
rely on others like a datacenter with their power, cooling and
networking infrastructure.
Plus you then need to support your hardware or have people do that.
I don't think a small group of radio amateurs should think they can do
a better job
than people like AWS, OVH, LINODE, Microsoft Azure, etc which have
dedicated
professionals working 24/7 to maintain, monitor and improve their
infrastructure.
