Personally, I prefer not to get in my customers' way. I'd 
much rather rely on other methods of keeping customers than 
holding them hostage due to renumbering nightmare. But 
that's just me.

Sure, I understand the motivation behind providers pushing 
customers into their own PA space, but things happen, and if 
a customer gets their own PI or PA space, it can become a 
problem if their sole reason for doing so is to break free 
of you :-).

That said, this typically applies to if your customers are 
service providers or large enterprises.

If your customers are broadband or SOHO users, then it's 
typical to have them under your PA space.

I agree, we should discourage NAT as much as possible.

We see NAT mostly in use by mobile operators (for obvious 
reasons). But unless AFRINIC have run out of space to 
allocate to them, I think they should be looking at using 
less NAT and more public space. 

Practically, it's only a matter of time before AFRINIC run 
out of space and these mobile providers are forced to NAT 
anyway, unless they start getting aggressive about IPv6.
