My assumption is that it is going to get _MUCH_ worse.  There is a  
lot of v4 address space allocated but not routed.  I suspect that the  
unrouted IPv4 space will begin to start showing up when people begin  
to realize that it is worth something to somebody.  The obvious  
implication of this is that you're going to see longer and longer  
prefixes being deaggregated out of what's in the routing tables today.

Yep.  I've been told there are ISPs out there that already are  
dealing with > 500K routes and are seeing convergence issues. And  
when these ISPs go to their vendors and ask for the roadmap for  
hardware, the upgrade deployment cycle outstrips the hardware  
development cycle.

However, maybe the folk from those ISPs were exaggerating... (hard  
for me to tell)
