Those hosts that can't reach the Internet typically can talk to other hosts that can, and even multiple private networks often link to each other. At a minimum, statistical uniqueness is necessary to avoid collisions between business partners even on a totally disconnected network. ULAs do not contribute to the global routing table unless ISPs allow them to in violation of the draft's wording and intent. The WG welcomes input on how to prevent this from occurring without invoking restraint of trade concerns. > No, that's not what I'm interested in.

I personally know of several dozen, and based on information I can't disclose, I'd say that at least half if not two thirds of the Fortune 1000 backhaul their Internet traffic -- many of them via IPsec VPNs over the Internet.
