too late NRO policy comparison chart:

Specifically APNIC and ARIN have /48 end-user assignments (PI)
policies in place, RIPE is still discussing this policy as of the last
meeting (if I recall correctly).

Sure, if they mis-plan or over-sell or acquire a competitor... there
are many scenarios that could include this sort of event.

At one point DISA/DoD was looking to get a /10 from <SOME RIR> ... I
don't that went anywhere, or is still under discussion. That'd
certainly make a dent in the available space though, eh?
