"Throw more Bandwidth at it" is a short-sighted answer. When we have say, 30,000 ports in our collection, how do you scale having to download each one to check? Lets see. If it were me, I'd take a bunch of machines, distribute them around the world at strategic network points, run a little "mapper" to map each box to the closest URLs in the ports collection, and have each box download them locally. *OR*, someone can write a patch to add something like SITE MD5 to the bsd ftpd, perhaps someone can then do the same to wu-ftpd and proftpd, and then write a small RFC snippet explaining why its a good idea and see if they can get it ratified. Then, you can have a single box at yahoo handle 30,000 ports by simply doing MD5 checks, rather than 30,000 ports by downloading each tarball.
