buy a 1U, put it in a colo center (should cost you about $50/month) and
proxy all your outbound mail from there. stop thinking of broadband as
anything other than a lastmile protocol between your house and your own
piece of the internet core.
or send SBC a copy of RFC 2317 every hour via a crontab. might not be
very effective but it would sure get you talked about. since you're a
customer they can't accuse you of spamming them...
