I haven't kept up with this as much as I should, but are the RIRs 
handing out PI space to orgs that don't have ASNs nowadays?

NPTv6 for free, or hassle + $cost for IPv6 PI (if it's even available) 
... to enterprises for whom OpEx is an infinitely more important factor 
than mythical devotion to an architecture that disappeared 15 years ago 
(namely, 99.9% of them) this is not even a decision.

If I went into the room and told my clients to do this I'd be laughed 
out of the room. It's way past time that people in the IPv6 ivory towers 
started paying attention to the real world.
