um... the internet routing architecture didn't explode in 1997 becuase
we'd didn't do this. meshed network edges need an igp, some sanity and
cooperative upstreams, otherwise you'll just have a very large very messy
subnet with not external routing.
Not true at all. With IPv6 there's plenty of ways to solve the problem. This is one:
http://www.ietf.org/internet-drafts/draft-hain-ipv6-pi-addr-03.txt
http://www.ietf.org/internet-drafts/draft-hain-ipv6-pi-addr-use-03.txt
It is frequently assumed that any address format that is not based
on provider aggregation will degenerate into the 'swamp' that came
to describe pre-CIDR IPv4, with the result that the routing table
grows unabated. The goal of this scheme is to allow sites to be
independent of any provider, while still allowing aggregation for
those who do not require explicit global routing policy. As a
result, there will need to be consistently applied rules for when a
prefix gets aggregated and when it doesn't. These will be discussed
in the recommendations section.

Well, it's a fairly minor dream. What I imagine is this: I have DSL. My
neighbour has DSL. We also both have WiFi APs that can reach each
other, and connect at order-of-magnitude faster than the DSL links.
What I dream is this: That we start routing internet across the link.
When I start pulling packets off the internet, they can come to me not
only through my own DSL but from hers as well. I think this boils down
to an ultimate simplicity what all FN / CWNers want to achieve.
What needs to happen before I can realize my dream. I need to get an
IPv6 address ... at least one ... for free. I need to be able to set up
multi-homing in my home router. I need to be able to advertise my
routing path to the internet. The internet needs to be able to handle
at a massive scale (since every neighbour connects...). We need a /lot/
more IP addresses than we have now. I need to use a /real/ IP address
because I can't route internet traffic through a NAT/site-local
address. I need to have an ad-hoc routing algorithm that can set up
this bridge and route across it really easily (because I'm not a
trained network admin). Forget about BGP, AS, etc., we need a way to
handle the massive overload of routes at local scale, at a regional
scale, at a global scale -- something that will scale gracefully as the
internet topology shifts from a tree to a massively connected mesh.
Please comment ... tell me what you think.

PS I'm cross-posting this to a bunch of lists because I don't know one it belongs on. If you think you know which is best, please tell me!
