Yes, there are ... as I see it the current routing protocols aren't
really up to handling the CWN vision. I think most CWN visions (correct
me if I'm wrong) involve multihoming by having as many nodes in the CWN
connected to the internet as possible.
How is this not a solved problem? Is there some extension you want to add
to BGP at this late date?

I certainly don't expect every CWN to purchase an ASN for starters ... How will the CWNs define the networks? With multihoming they won't be trees ... setting up multihoming is hard enough when you are a big corp or an ISP and you can isolate the borders. I'm talking about an (inter)net with a potentially ever-expanding edge, where leafs can turn into nodes relatively easily by plugging their DSL into their access point, where two towns with a rural swath in between might find themselves connected by a mesh through that area. Route the packets through the CWN instead of through the ISPs.
