I'm saying that as it stands, they could request space from ARIN for 
internal LSN space and then turn around and use the /10, which would be 
false justification, but there isn't a way for us to defend against it 
without the policy limiting LSN justifications. It's important to note 
that this limitation only would stop people from justifying IPv4 
utilization on the inside of their LSN implementation; compensated with 
us giving a /10 to the world for that specific purpose.  I think you 
gathered this on my other email.
