Nope. If you request foo.com and you have up to two days earlier
visited bar.com, you won't hit the root servers. Only the .com
servers.
which would make it 'NON-cached'

People have a tendency to call other people in the same area codes
more often than people in other area codes. That ought to help load on
the root servers.
that is if your caller base are residential.
call centers do not follow this.
Anyway, a single server can easily handle 1000 queries per second. If
you add even 0.1 cent to the call setup fee to pay for the lookup and
you keep the servers at 100 qps average, you are looking at $8640 a
day per server.
Or look at it the other way around, if you allocate $1000 a month to
run a server, and that server performs at 100 qps average, each call
costs you .0004 cent extra.
which if you want redundancy (like was mentioned already)...
using the 'root servers' as a *model*
"someone would have to have this expense/headache to maintain"

i'm not sure why i seem to be unable to get my point across (even with
multiple attempts), so i will just not try.
good luck
