I'm in the process of shutting down Word2[1], an MMO scrabble-like word game we built for Node Knockout back in 2010. The game's world is amazing - ~265MM tiles, ~123MM played words, over 1MM unique players. Once all personally identifiable information has been removed, I'd like to provide it to interested parties to play with. The clean dataset will be ~15GB compressed - what's the preferred way to share multi-GB files these days? Bittorrent, S3 (probably Requester Pays unless there's another option with manageable costs), or something else? Suggestions welcome.
