I think that a lot of ppl uses ftp to download packages and since rsync doesn't come with the base system, ftp downloads are more handy

Yep, it could be useful to create a $PACKAGE.md5 for each package on the directory.. but it'd end up filling it with a lot of files, and when someone tries to access the dir, it'd take double the time to download the contents (think of slow connections.. i'm on 512k and it takes a while to read the contents). So i think that a file containing all the md5 sums would be the right choice.
I hope that something like this is going to be done, so we can rely on our packages' downloads.
