Is there a way to add torrents with the same info_hash as seperate downloads? Because of how private trackers work, you cannot have multiple trackers in one torrent; It will mess up stats the tracker sees and you will be considered to "ratio cheat".

If possible, I'd prefer discussing things over IRC; Do we have an official IRC channel?

It's not possible in Tixati and I think BitTorrent isn't designed to support this. Info hash is used as unique identifier, Tixati wouldn't know to which torrent incoming connections should go, unless each torrent would use different incoming port. Theoretically it's possible but I doubt that any bittorrent client can do this.
