I have all of those on a home ADSL connection, although I doubt you can get that from many ISPs, mine is about 20% more expensive than the cheap ones and didn't even offer non-static IPs until about a year ago. If you use your ISP's smarthost you can probably get away without reverse DNS, I doubt mail servers are going to leave their mail undelivered because the receiving MX is in a dialup range. BTW, you forgot 4), the biggest obstacle with residential ISPs: blocking of port 25 both ways, which is luckily becoming more and more common, even to the point were the telecommunications regulation authority here officially recommends it to ISPs.
