An interesting move it seems now that comcast have been ordered to halt this deceptive practice.
http://torrentfreak.com/eff-tool-hunts-bittorrent-throttling-isps-080802/As was revealed in the stats from Project Glasnost, Cox is also throttling heavily. So, while some are popping the champagne corks over this victory, others are still working hard to keep our ISP’s honest, and ensure that their customers are getting what they paid for.
The latest of these, is a project called Switzerland by the EFF. Still in very early alpha, it’s an attempt to not just detect sandvineing by an ISP, but other forms of throttling as well. Unlike Glasnost, which uses a central server and known torrent streams to detect activities from the ISP interfering, this will use a more decentralised method, where peers running Switzerland swap information about the packets they send to other Switzerland users, in encrypted data packets sent via a central server.
Would be nice if this was expandable to cover other networks but at least it makes possible the detection and then potential remedy for those being hit by greedy iSP companies.
