Super seeding mode and web seeding were originally developed by the BitTornado group.
It is programmed using Python, for platform independence. Due to this, it can be used server-side on servers which support python applications, without having root access. Torrentflux is a popular PHP front-end for BitTornado, but because of its nature being inherently resource-intense, most shared web hosts block such scripts.
BitTornado developer John Hoffman decided to ban BitComet users from accessing his client as he claims it exploits super-seeds.
