Duh.

Like a T1 doesn't require a POP. Like T1's and their associated CSU/DSU's
and such don't break (tell that to several of my customers who will get a
hearty chuckle out of that one). Like they don't need air-conditioning and
other support services.

True, but to be effective they must be available on demand and the user
shouldn't have to wait until your auto-dialer feels this is a good time to
deliver the service.

I have found that my 128k connection very seldom gets congested even with
high traffic. Other traffic choke points usualy limit the amount of
traffic that I see. Even when one of my customers runs their resume tracking
program (which will saturate a ethernet easily in testing) can seldom
saturate the line for more than a few seconds.

Ah, so cracker is not a true commercial model but rather a hybrid then?
You pay for some services and a 3rd party donates the rest?

I'm wondering about your co-location machine, from your comments above it
must be sitting in a field since you don't pay rent (or was that your way of
saying somebody else pays the rent for you?). Is this so? Since so many of
your utilities and physical plant are donated I have to question the
accuracy and utility of your figures as well as the applicability of those
figures to a true commercial enterprise.

Whether you have realized it or not, all those seemingly great freebies and
perks for nothing actualy make the remailer less stable because your
operation relies on the good feelings of a 3rd party which can be used to
Mallet's advantage.
