BitLet is a experimental java based online service which offers free service of torrent downloading without a client on our computer. You can choose options like incoming Port and maximum upload rate. But unfortunately this is only good for leechers as it does not have a upload/seeding service as yet.
To download the torrent file you choose, right click on the download torrent link, copy the link location (e.g. http://www.example.org/file.torrent) and then paste it in the input box at bitlet.org. Then you have only to click on “Download torrent” button. Simple enough.
