Well, let's put it this way: the data center community has, for better or worse, decided that BGP is their protocol of choice.  Frankly, I find it mildly nauseating, but it's very clear that they are going to use BGP regardless of what you and I say.  Yes, there are more than one of them going this way, they are large and well-funded.  It's going to happen.

Now, again, we can block off a range of numbers, or data center folks are going to end up squatting on public ASNs.  And if that happens, we will end up being asked to implement ASN NAT, at which point we can no longer ensure global uniqueness.
