It depends a lot on the traffic. If it's 100 messages a day, then it's
a few hundred times the traffic on a list with a couple of messages a week.
It also depends on the kind of box you're running it on (386? Sparc 20?).
So, if I were looking to cut down on the CPU time required and the traffic,
I'd do this:

1. ecnrypt with the keys of every recipient to send out one encrypted
messages that every recipient can decrypt.

2. consider using a daily digest (or digest every few hours).

Anyway, if you have more than a dozen people on the mailing list whom
you don't know personally, you should *assume* that at least one of them
is a narc and/or an asshole who'll decrypt it and pass it on to others.
