This is just not realistic in most cases. It's hard enough to get people to understand "Click on the FileSonic link". Normal people do not have Bittorrent clients installed. I'd try FTP before Bittorrent.
Most people are used to install software when it is just "download, open, install". When installed, it associates with .torrent files and it is effectively as easy as clisking a link.
Most companies forbid bittorrent traffic because it saturates the local intranet, especially on wifi networks. And because they perceive bittorrent to be illegal.
OK, thanks very much for the recommendation, I will try that. I never even considered using bittorrent for 1 to 1 file transfers. Does require that clients are willing to use bittorrent, which won't always be the case but it's good to have options.
I do realize there are still other cyberlockers up, but it seems highly possible they are all going down soon, disabling service to the US, or will be severely feature limited.
I am very serious, it is well designed for that, especially if you are sending to several people.
