Not a good definition.  "Can actually work in practice" for whom?

Sparse allocation of /48s on demand to anyone willing to pay a yearly  
registration fee is a perfectly viable distribution model.

Allocating /12s to national PTT or equivalents in each country on the  
planet and letting them deal with allocations in country is a  
perfectly viable distribution model.

Auctioning space to the highest bidder is a perfectly viable  
distribution model.


All of these "work in practice".

What is most likely _not_ going to work in practice is allocating  
blocks to ISPs and requiring all enterprises obtain PA address space  
from those ISPs.  Given the liberalization of PI policies either  
implemented or being discussed in all the RIRs, this would appear to  
be understood.
