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.
