ZbigZ lets you download via the BitTorrent protocol without having to install a BitTorrent client. It does so by first downloading the file via BitTorrent, then lets you download it via the usual HTTP on your web browser. If another user has already downloaded the file, then the file will be retrieved from its cache, which will be much faster. Free users are subjected to a download speed limit of 150KBps in download, and maximum file size of 8GB. Paid users do not have such limitations.
