Lower your bandwidth costs using P2P

If you have largish files you want to share, but are concerned with the speed of your upload link or bandwidth costs there are several options:

• You can post a Torrent file and the consumer can use a Torrent client; I like uTorrent. The downside is that this requires a client-side program be installed by the user.
• You can use a CDN proxy; I like the free Coral Content Distribution Network. The downside is that it requires port 8080 be open at this time (promises of just-port-80 long pending).
• You can now use RedSwoosh to proxy the links. This also requires a client-side download, but they serve it up automatically.
