I am not sure I am following you here. Are you saying that we should
re-adress customers so that we get larger blocks of PA space to give to
mulithomed customers? 

I think that re-addressing is pretty hard to do in any larger scale,
although that would certanly help some other issues. 

another good start would be to start reclaiming space that has been handed
out from various ISPs old B-space and later taken with the customer. I
know a few operators that have done that (including us to some extent),
and it's a rather demanding task but will help the operators and reudce
the routing table as well.
