There are many prefixes which are demonstrably useless in the global table 
(e.g. most of 7046).  If you are really interested in reducing the size of 
the table, why not go after those?  Instant gratification and all that.

But I thought the problem is not *size* of the table, but *changes* in the 
table.  With zero updates, a BGP table of double the current size would not 
bother any core router on the 'Net today.

So, let's work on things like progressive flap dampening.  I believe you 
suggested this before, Sean?
