You can accomplish the same thing by using Spamhaus's PBL. See http://www.spamhaus.org/pbl/index.lasso "The Spamhaus PBL is a DNSBL database of end-user IP address ranges which should not be delivering unauthenticated SMTP email to any Internet mail server except those provided for specifically by an ISP for that customer's use. The PBL helps networks enforce their Acceptable Use Policy for dynamic and non-MTA customer IP ranges"

Very true. Though I have found cases of false positives and false negitives. From experience, Spamhaus is generally not friendly to removing false positives. The goal of DynaStop is to do its job with minimal collateral damage (preferably none). For the record, I am not an RBL advocate as I see many issues about RBL that are simply injust and totalitarian. I avoid this by putting the authority and responsibility on the administrator, not a third party with an "I don't care" attitude.
