Geo addressing sounds interesting on the surface, but every proposal  
seems to require a new economic model. I find it difficult to believe  
that will happen anytime soon.

The other problem with using IXs that immediately comes to mind is  
that you are essentially multihoming to a single piece of  
infrastructure. Not really resilient in my mind :)
