Have you looked at also making the Java applet support bittorrent for just file downloads itself? If no one is doing that already, a really slick looking web interface for file downloads might get more corporations interested in using BitTorrent for their own file distribution.
You need to get out and start showing this to people. You may even want to start talking to some of the CDN companies to see if they want to license this. Some of them already have other approaches for P2P bandwidth sharing, but it would be another bag of tricks with a decent user experience that companies would consider for large files.
Even if the CDN people don't like this, half the torrent sites out there would be better served if they had a tool like yours for quick downloads of the torrent.
I'd really focus on selling the improved user experience side, though. Ideally the end user doesn't even know that a .torrent is involved in the download. It's just another background/confusing aspect that users don't need to see.
I think companies will need a way to configure a fallback option for when BT isn't working for the user, but I think that's all just features that could eventually be worked into the mix pretty well.
