GetRight 6.0 and higher supports BitTorrent™ downloads.
BitTorrent is different: you communicate with other people who are downloading the same file ("peers" in BitTorrent lingo). Instead of downloading from one place, you will download small pieces of the file from different peers--and you'll connect to a bunch of peers, up to 20 in GetRight. There often is a "seed" peer that has the whole file, to get the file started and send pieces so all the parts are available to be passed around between peers.
In addition to downloading pieces from different peers, you will be sharing and uploading the pieces you've already downloaded back to other peers. So if peer A has piece 1 and you download it, peer B may later ask you to give it piece 1. This sharing is required and is part of the whole BitTorrent protocol, there's no way to not share. The faster you share pieces with a peer, the faster it will allow you to download its pieces.
Another advantage is that BitTorrent has built in information so the pieces of the file can be validated to make sure it is 100% the same as the original file (another big improvement over HTTP/FTP.) You should never have a bad BitTorrent download.
Because of how BitTorrent works, it is better if your computer can be listening for other peers trying to download the same files. GetRight does try to set this up automatically (if your router/firewall supports Universal Plug-and-Play) but not all versions of Windows or routers allow this. GetRight and Port Forwarding.
