A very good point.  But geez, how are the CFO and shareholders going to
feel about $8.14 million spent over the year in the name of slowing down
spam for everybody else on the net?  If that ever showed up as a balance
sheet line item (and you're right, it probably wouldn't), they'd be mad.

And that assumes the level of spam stays constant.  I've heard horror
stories that spam global spam volume doubles every few months.  I can only
measure my own spamassassin mailbox, where I got 150 spams yesterday.

Your point is still well taken, bandwidth isn't precious to everybody.
