They’d only be able to do one such agreement per routing environment. Managing that would be _UGLY_ for the first one and __UGLY__ at scale for anything more than one. It also pretty much eliminates potential for geographic diversity and anycast for a provider in a local geography. Certainly not something I’d choose to do if I were OpenDNS unless someone arrived with a very large truck full of gold, diamonds, or other valuable hard assets. Owen
