        I'd be comfortable with more than 8192 provided 
the routing system still met the criterion Randy outlines below.

        Yep.

        Some few folk think that somewhere between 100K and 300K prefixes
it isn't stable to have "fairly stable routing which converges
predictably in reasonable time" when using current BGP and current
BGP algorithms.  Those folk are credible, but I haven't seen any
equations yet myself.
