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.

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? (I don't have
the base quantity handy, would someone please provide?)

Why $2M? 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)?

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).
