and anyway, the average visit to facebook is still more data than the 
entire ipv6 route table at the moment.

we might also want to speed up bgp handling by routers a bit in the 
future, as some are DAMN SLOW in processing a few hundred thousand sets of 
data... (no people, it's NOT acceptable when a 200k box takes more than a 
few milliseconds to process whats basically just a few megabytes of data 
coming in over 10ge pipes and put it into a route table in ram ;)

time to put all those suppliers a pepper in their **** and simply stop 
buying their stuff if they keep selling obsolete junk.

end-to-end PI is the way to go.
