An old topic, but searching revealed this was the recommended topic for this discussion. As far as I/O goes - no reason NMM couldn't pause seeding while a game is running. You could also limit the bandwidth and maximum number of connections. The beautiful part about this arrangement is that each one of the NexusMods file servers can run a torrent client to seed the torrents. By doing this, you can utilize the bandwidth of all your servers (while limiting it if necessary) as well as some dedicated servers if you like. And by using the file servers, you can just point the torrent to the file that's already on the server, reducing storage space and replication time. As far as security, most trackers use Passkey's (a URL variable tacked onto the torrent announce URL that is unique to each user) as well as IP monitoring. You can also use client ID filtering (each different torrent program sends an ID unique to the program), ensuring only NMM clients can access the tracker. By disabling peer exchange between clients, only reporting premium servers as peers to premium members, and implementing IP checking on the premium servers, you can ensure the premium servers are limited to premium members. The other big advantage this has is mod integrity checking. NMM could verify the integrity of the downloaded mod file based on the torrent, and redownload any chunks that are corrupt or incorrect. Besides offering incentives in the form of credits or whatnot, you can also limit the number of peers per file, the download speed of the file, and the number of simultaneous downloads. For torrents, you can relax these restrictions while seeding is enabled, and enforce them when seeding is disabled. Or you could just make it so enabling torrent mode also enables seeding. EDIT You should move this topic to the Open Beta feedback forum since it would be a client implementation more than a website implementation. EDIT2 Maybe rename the title, I think the author was trying to say "Support downloading large mod files via BitTorrent in Nexus Mod Manager" but wasn't familiar with the terminology.
