Creating the debian mirror for that project we discussed was
very easy.  The only hard part was waiting for the downloads to
complete.  Here's what I did:

    $ sudo apt-get install apache debmirror
    $ sudo mkdir /var/www/debian
    $ sudo chown suter:suter /var/www/debian
    $ debmirror /var/www/debian --progress --md5sums --passive --host
    mirror.pacific.net.au --method=ftp --root=/debian

And presto - after all the waiting - one debian mirror up and running!
