Mac Deity 2.1 - 33k - Downloads a series of images, saving them to your hard drive. New in 2.1, support for "virtual" servers, a referrer is sent in the header, and the http status code is used to decide whether or not to save an image (404 not found, will not result in the page being saved to disk).

Luna 1.3 - 1000k - Takes a list of wingates/proxies, and loads a webpage with each one of them.
Missing things though: I don't think it loads all the images on the page, or sends a referring address in the http headers, or even if it sends any headers that let the site know what browser you're using. All of which it SHOULD be doing if you want to make any money ripping off banner programs. It should also load the second page from the site, which is what most porn sites use to track how many visitors you're sending them.
This program is a cool idea, but at the current version I would NOT use it seriously, unless I wanted to get caught. ;)

McAuth 1.0d7 - 748k - Web brute force hacker. One of the only ones for the Mac OS. It takes a list of username and password combinations, and tries them out on a password protected part of a website. Looks good, it lets you choose what browser you want the site to think you're using, and lets you choose the referer info. It's biggest problem however, is that it is limited to only 4 proxies. (macman.net ignores an ip after around 5 bad passwords, so McAuth would get to try 20 passwords on it, then have to take a break)
