Nathan,
The best (longer term) solution is to use bittorrent for such files. This way everybody downloading will contribute some bandwidth while getting the file. You should create a 'torrent' file and point people to a bittorrent capable piece of software.
By the way, I've placed the 7slotgrille multimedia files on shareaza (gnutella & edonkey) p2p for everybody to enjoy. My shareaza machine is not very stabel at the moment, the latest beta I'm running is quite flaky.
