wow. so with current-gen hardware like amd64 chips or even intel p4's,
and a gig of ram, i should be able to push at least 600m per month,

requests per second; i'd love to double or triple that though, if
possible.
Just looking round my kit...
"Busiest" (word used advisedly!) system is a DNS system which is
currently running between 120-150 LVS conns/seq (equates to about 600
queries/sec). It's a P4 3.0GHz, 2GB RAM. Those rates are equivalent
roughly to between 300 and 400 million conns/month, or about 1.5
billion queries/month.
Connection table holds just over 45000 entries (right now).
'free' reports:
[root@frontend01 ~]# free
total used free shared buffers cached
Mem: 2075344 1782160 293184 0 131804 1378988
-/+ buffers/cache: 271368 1803976
Swap: 4208928 0 4208928
This is also running a MySQL server full of DNS data, so the bulk of
the used memory is the query cache for MySQL.
Whichever way I skin this, it isn't breaking a sweat - 1 minute load
rarely exceeds 0.5. I don't yet know how far I could push this, but
I'll know in the next few months how it copes with bigger load as I'll
be moving more authoritative addresses over to it.
