Route table growth and hardware to the filter

I'm willing to bet that Cisco's sales team is pushing back a little on
this enhancement.  Given the choice between prolonging the usefulness of
Sup2 for another year or two versus selling a massive amount of new
Sup720-3BXLs, I'm betting they'll do the later.

There's a couple of feature requests open at Cisco that would do this. 
Rodney Dunn (at Cisco) pushed quite hard for these but couldn't get any 
traction. As he's previously pointed out it would have if people would 
vote for them (attach a case to).
