I was being serious... the current 'bgp unconstrained dies' problem
isn't such a problem if you have (today):
  4-8 cores
  16 gb ram
  ssd
  gigabit ethernet

or as you'd call this, your desktop computer... trying to do this on a
600mhz mips with 512mb ram is, clearly, a problem.  put modern
hardware to work and it gets simpler. Yes, the above addresses
getting/sending 'rib' data, it doesn't address programming a FIB, but
rethinking the programming of the fib a bit could, I bet, even get us
to a palatable point for a longer while, in a relatively short period
of time.
