Yes a very big unless. Multi-core processors are already available that would make very large BGP convergence possible. Change the algorithm as well and perhaps add some multi-threading to it and it's even better.
Anyone have a decent pointer to something that covers the current state of the art in algorithms and (silicon) router architecture, and maybe an analysis that shows the reasoning to get from those to realistic estimates of routing table size limits?
no, not exactly - but take a look at: Report from the IAB Workshop on Routing and Addressing http://tools.ietf.org/html/draft-iab-raws-report Routing Research Group Active Proposals http://www3.tools.ietf.org/group/irtf/trac/wiki/RoutingResearchGroup On Compact Routing for the Internet http://www.caida.org/publications/papers/2007/compact_routing/compact_routin... - Lucy

so putting a stake in the ground, BGP will stop working @ around 2,500,000 routes - can't converge... regardless of IPv4 or IPv6. unless the CPU's change or the convergence algorithm changes.
That is a pretty big "unless" .
