I tend to agree, the numbers I threw around earleir were strictly first-order approximations for raw sizes. Second-order would include performance issues and algorithm requirements. I see that Vadim ihas already arrived there. > I would say that a computing device capable of doing today's border routing > policies at 1M updates per second is well into the realm of science > fiction. The other item usually included at this level should be bandwidth requirements. What is the size of an update, and how many Gbps load would be generated, at a rate of 1M updates per second?

From price ranges in the current market, I would think that they'd have to hit under $200K. Actually, I would have a difficult time convincing clients of anything over an additional $60K. This gets back to my earlier question, how many backbone routers are there (nearest order of magnitude should suffice here)? > The question of profitability of cheese mining on the Moon is > irrelevant, because Moon isn't made from cheese. Typical rough market guidelines are that development cost must be less than 1% of total market size or the project is a non-starter, business-wise. Typical costs for this sort of project are $1M to $3M, over 8 months, with COGm at about $50 (relative to a minimum Number of Goods sold [NOGs] and assuming that it is technically feasible).
