This is certainly the theory.  However, if you are a growing ISP, 
renumbering from PA space from another LIR to your own PI space or 
LIR/PA space can be - depending on how your customers are configured - 
pure pain.

The portability associated with PI space is also important in one other 
view, in that it allows the holder to switch providers quickly and 
efficiently.  There's no tie-in of any form, and this is something which 
is extremely important to business.
