I ran into a similar question a while back: 
But there I was wondering / discussing if requesting a prefix larger 
than /64 was possible to allow using that routed prefix to host i.e. a 
VPN solution.

Prefix delegation of GUA prefixes implemented in Neutron apparently: 
And to me prefix delegation of a global unicast address prefix (GUA) 
seems like the cleanest solution.
