(company, family, enterprise) which wants it?

fundamental physical limits that constrain technology.

Once you add that bit of reality to it, the scaling requirement goes
down substantially. Wouldn't you agree?

My feeling is that the question isn't how much memory, but rather how
much CPU and bandwidth is necessary to deal with routing thrash.

That's right. The issues are the complexity of the routing computation
and the convergence time/stability of the routing computation as a
