That's like saying that the impression that multihoming == higher uptime is 
a fallacy because it can easily be deployed poorly.  Anycast does increase 
uptime when done intelligently.

However, that notwithstanding, I think the concerns about potential abuse 
of this policy are justified, but instead of claiming that anycast is too 
hard we really should try to craft the policy such that abuse is not 

For example, the issue has less to do with an entity not being able to 
justify enough space for their entire enterprise and more to do with the 
fact that they cannot carve a /24 out of their space for fear of having it 
filtered.  What if an org was required to already have an ARIN allocation 
under the normal criteria to qualify for an anycast block?
