Non-profit IP Registry

Two questions come to mind with this:

   How will portable/non-portable address space be effected. Does the mean
that if I have non-portable address space, I can charge customers for
address space, and if it is portable, they have to pay $2500 per /24 to
have it registered to them?

   If an entity has address space already and does not require more space,
do they have to pay the fee or is this going to be grandfather claused? I
know with domain names it was not that way, but that is only 50 bucks,
$2500 or more could put a lot of business off the net.

I guess this will make the routing table size come to a sudden and
screaching halt!
