We keep stuck in the past because we won't deploy
realistic things but keep
discussing about how it could work in an ideal situation and with infinite
human resources (financial resources as well in the past, but that is less of a
problem now).
The current discussion quickly moved on from creating a new more usable
backbone network into enterprise-grade systems, worldwide
announcement of the entire address space, use of hardware routes rather
than VMs, etc etc.
I don't see how deploying some actual hardware is unrealistic. A VPS-based solution
will not scale well because in the VPS, you're buying into a system that's
oversubscribed by design and you're at the mercy of the software layer inside of the
VPS system the host is using. 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.
