There are at least 2 problems to be addressed (given that you believe
'too many routes will crush the dfz routers')... both number of routes
and speed/number of updates.  So, adding more MEMORY (pick your type
DRAM/SRAM/bah) is only solving one of the problems. Additionally, most
moderm DFZ-placed platforms aren't necessarily 'RAM' limited, some of
the limits exist in hardware forwarding elements (TCAM/CAM/ASIC
systems).

Anyway, Suresh's followup has a decent info as well, you might locate
the RRG and RAM/RAWs working group meeting outputs as well:
